SimulationControls Properties
A simulation controls UI component creates buttons to control simulation in an app. By changing property values, you can modify the appearance and behavior of a simulation control component. Use dot notation to refer to a specific object and property.
Simulation Controls
StartText
— Start button label
'Run'
(default) | character vector | cell array of character vectors | string scalar | string array
Start button label, specified as a character vector, cell array of character vectors, string scalar, string array, or 1-D categorical array. Specify a character vector or string scalar to label the button with a single line of text. Use a cell array or string array to label the button with multiple lines of text. Each element in the array represents a separate line of text. If you specify this property as a categorical array, MATLAB® uses the values in the array, not the full set of categories.
Example: uisimcontrols('StartText','Start Sim')
PauseText
— Pause button label
'Pause'
(default) | character vector | cell array of character vectors | string scalar | string array
Pause button label, specified as a character vector, cell array of character vectors, string scalar, string array, or 1-D categorical array. Specify a character vector or string scalar to label the button with a single line of text. Use a cell array or string array to label the button with multiple lines of text. Each element in the array represents a separate line of text. If you specify this property as a categorical array, MATLAB uses the values in the array, not the full set of categories.
Example: uisimcontrols('PauseText','Pause Sim')
ContinueText
— Continue simulation button label
'Continue'
(default) | character vector | cell array of character vectors | string scalar | string array
Continue button label, specified as a character vector, cell array of character vectors, string scalar, string array, or 1-D categorical array. Specify a character vector or string scalar to label the button with a single line of text. Use a cell array or string array to label the button with multiple lines of text. Each element in the array represents a separate line of text. If you specify this property as a categorical array, MATLAB uses the values in the array, not the full set of categories.
Example: uisimcontrols('ContinueText','Cont.')
StopText
— Stop button label
'Run'
(default) | character vector | cell array of character vectors | string scalar | string array
Stop button label, specified as a character vector, cell array of character vectors, string scalar, string array, or 1-D categorical array. Specify a character vector or string scalar to label the button with a single line of text. Use a cell array or string array to label the button with multiple lines of text. Each element in the array represents a separate line of text. If you specify this property as a categorical array, MATLAB uses the values in the array, not the full set of categories.
Example: uisimcontrols('StopText','Stop Sim')

Simulation
— Simulation representation
empty (default) | simulink.Simulation
object
Simulation representation that provides an interface to control the simulation of a
Simulink® model, specified as a Simulation
object.
Font and Color
FontName
— Font name
system supported font name
Font name, specified as a system supported font name. The default font depends on the specific operating system and locale.
If the specified font is not available, then MATLAB uses the best match among the fonts available on the system where the app is running.
Example: 'Arial'
FontSize
— Font size
positive number
Font size, specified as a positive number. The units of measurement are pixels. The default font size depends on the specific operating system and locale.
Example: 14
FontWeight
— Font weight
'normal'
(default) | 'bold'
Font weight, specified as one of these values:
'normal'
— Default weight as defined by the particular font'bold'
— Thicker character outlines than'normal'
Not all fonts have a bold font weight. For fonts that do not, specifying
'bold'
results in the normal font weight.
FontAngle
— Font angle
'normal'
(default) | 'italic'
Font angle, specified as 'normal'
or 'italic'
.
Not all fonts have an italic font angle. For fonts that do not, specifying
'italic'
results in the normal font angle.
FontColor
— Font color
[0 0 0]
(default) | RGB triplet | hexadecimal color code | 'r'
| 'g'
| 'b'
| ...
Font color, specified as an RGB triplet, a hexadecimal color code, or one of the options listed in the table.
RGB triplets and hexadecimal color codes are useful for specifying custom colors.
An RGB triplet is a three-element row vector whose elements specify the intensities of the red, green, and blue components of the color. The intensities must be in the range
[0,1]
; for example,[0.4 0.6 0.7]
.A hexadecimal color code is a character vector or a string scalar that starts with a hash symbol (
#
) followed by three or six hexadecimal digits, which can range from0
toF
. The values are not case sensitive. Thus, the color codes"#FF8800"
,"#ff8800"
,"#F80"
, and"#f80"
are equivalent.
Alternatively, you can specify some common colors by name. This table lists the named color options, the equivalent RGB triplets, and hexadecimal color codes.
Color Name | Short Name | RGB Triplet | Hexadecimal Color Code | Appearance |
---|---|---|---|---|
"red" | "r" | [1 0 0] | "#FF0000" |

Position
Position
— Size and location
[100 100 161 54]
(default) | four-element vector
Size and location, specified as a four-element vector of the form [left
bottom width height]
. This table describes each element in the
vector.
Element | Description |
---|---|
left | Distance from the inner left edge of the parent container to the outer left edge of the simulation controls |
bottom | Distance from the inner bottom edge of the parent container to the outer bottom edge of the simulation controls |
width | Distance between the right and left outer edges of the simulation controls |
height | Distance between the top and bottom outer edges of the simulation controls |
All measurements are in pixel units.
InnerPosition
— Size and location, excluding labels and margin
[100 100 161 54]
(default) | four-element vector
This property is read-only.
Size and location, specified as a four-element vector of the form [left
bottom width height]
. This property is equivalent to the
Position
property.
OuterPosition
— Size and location
[100 100 161 54]
(default) | four-element vector
Size and location, specified as a four-element vector of the form [left
bottom width height]
. This property is equivalent to the
Position
property.
Layout
— Layout options
empty LayoutOptions
array (default) | GridLayoutOptions
object
Layout options, specified as a
GridLayoutOptions
object. This property specifies options for
components that are children of grid layout containers. If the component is not a child
of a grid layout container (for example, it is a child of a figure or panel), then this
property is empty and has no effect. However, if the component is a child of a grid
layout container, you can place the component in the intended row and column of the grid
by setting the Row
and Column
properties on
the GridLayoutOptions
object.
For example, this code places simulation controls in the third row and second column of its parent grid.
g = uigridlayout([4 3]); s = uisimulationcontrols(g); s.Layout.Row = 3; s.Layout.Column = 2;
To make the simulation controls component span multiple rows or columns, specify the
Row
or Column
property as a two-element
vector. For example, this scope spans columns 2
through
3
:
s.Layout.Column = [2 3];
HorizontalAlignment
— Horizontal alignment of icon and text
'center'
(default) | 'left'
| 'right'
Horizontal alignment of the icon and text, specified as 'center'
,
'left'
, or 'right'
. The horizontal alignment is
relative to the area inside the borders of the button. Setting this property when the
text spans the full width of the button has no apparent effect in the UI.
VerticalAlignment
— Vertical alignment of icon and text
'center'
(default) | 'top'
| 'bottom'
Vertical alignment of the icon and the text, specified as
'center'
, 'top'
, or 'bottom'
.
The vertical alignment is relative to the area inside the borders of the button. Setting
this property when the text height fills the height of the button has no apparent effect
in the UI.
IconAlignment
— Location of button icon
'left'
(default) | 'right'
| 'center'
| 'leftmargin'
| 'rightmargin'
| 'top'
| 'bottom'
Location of the button icon, specified as one of the values in the drop down menu.
Interactivity
Visible
— State of visibility
'on'
(default) | on/off logical value
State of visibility, specified as 'on'
or 'off'
,
or as numeric or logical 1
(true
) or
0
(false
). A value of 'on'
is equivalent to true
, and 'off'
is equivalent to
false
. Thus, you can use the value of this property as a logical
value. The value is stored as an on/off logical value of type matlab.lang.OnOffSwitchState
.
'on'
— Display the object.'off'
— Hide the object without deleting it. You still can access the properties of an invisible object.
Enable
— Operational state
'on'
(default) | on/off logical value
Operational state, specified as 'on'
or 'off'
,
or as numeric or logical 1
(true
) or
0
(false
). A value of 'on'
is
equivalent to true
, and 'off'
is equivalent to
false
. Thus, you can use the value of this property as a logical
value. The value is stored as an on/off logical value of type matlab.lang.OnOffSwitchState
.
If you set this property to
'on'
, the app user can interact with the component.If you set this property to
'off'
, the component appears dimmed, indicating that the app user cannot interact with it.
Tooltip
— Tooltip
''
(default) | character vector | cell array of character vectors | string array | 1-D categorical array
Tooltip, specified as a character vector, cell array of character vectors, string array, or 1-D categorical array. Use this property to display a message when the user hovers the pointer over the component at run time. The tooltip displays even when the component is disabled. To display multiple lines of text, specify a cell array of character vectors or a string array. Each element in the array becomes a separate line of text. If you specify this property as a categorical array, MATLAB uses the values in the array, not the full set of categories.
ContextMenu
— Context menu
empty GraphicsPlaceholder
array (default) | ContextMenu
object
Context menu, specified as a ContextMenu
object created using the uicontextmenu
function. Use this property to display a context menu when
you right-click on a component.
Callbacks
CreateFcn
— Creation function
''
(default) | function handle | cell array | character vector
Object creation function, specified as one of these values:
Function handle.
Cell array in which the first element is a function handle. Subsequent elements in the cell array are the arguments to pass to the callback function.
Character vector containing a valid MATLAB expression (not recommended). MATLAB evaluates this expression in the base workspace.
For more information about specifying a callback as a function handle, cell array, or character vector, see Create Callbacks for Graphics Objects.
This property specifies a callback function to execute when MATLAB creates the object. MATLAB initializes all property values before executing the CreateFcn
callback. If you do not specify the CreateFcn
property, then MATLAB executes a default creation function.
Setting the CreateFcn
property on an existing component has no effect.
If you specify this property as a function handle or cell array, you can access the object that is being created using the first argument of the callback function. Otherwise, use the gcbo
function to access the object.
DeleteFcn
— Deletion function
''
(default) | function handle | cell array | character vector
Object deletion function, specified as one of these values:
Function handle.
Cell array in which the first element is a function handle. Subsequent elements in the cell array are the arguments to pass to the callback function.
Character vector containing a valid MATLAB expression (not recommended). MATLAB evaluates this expression in the base workspace.
For more information about specifying a callback as a function handle, cell array, or character vector, see Create Callbacks for Graphics Objects.
This property specifies a callback function to execute when MATLAB deletes the object. MATLAB executes the DeleteFcn
callback before destroying the
properties of the object. If you do not specify the DeleteFcn
property, then MATLAB executes a default deletion function.
If you specify this property as a function handle or cell array, you can access the object that is being deleted using the first argument of the callback function. Otherwise, use the gcbo
function to access the object.
Callback Execution Control
Interruptible
— Callback interruption
'on'
(default) | on/off logical value
Callback interruption, specified as 'on'
or 'off'
, or as
numeric or logical 1
(true
) or
0
(false
). A value of 'on'
is equivalent to true
, and 'off'
is equivalent to
false
. Thus, you can use the value of this property as a logical
value. The value is stored as an on/off logical value of type matlab.lang.OnOffSwitchState
.
This property determines if a running callback can be interrupted. There are two callback states to consider:
The running callback is the currently executing callback.
The interrupting callback is a callback that tries to interrupt the running callback.
MATLAB determines callback interruption behavior whenever it executes a command that
processes the callback queue. These commands include drawnow
, figure
, uifigure
, getframe
, waitfor
, and pause
.
If the running callback does not contain one of these commands, then no interruption occurs. MATLAB first finishes executing the running callback, and later executes the interrupting callback.
If the running callback does contain one of these commands, then the
Interruptible
property of the object that owns the running
callback determines if the interruption occurs:
If the value of
Interruptible
is'off'
, then no interruption occurs. Instead, theBusyAction
property of the object that owns the interrupting callback determines if the interrupting callback is discarded or added to the callback queue.If the value of
Interruptible
is'on'
, then the interruption occurs. The next time MATLAB processes the callback queue, it stops the execution of the running callback and executes the interrupting callback. After the interrupting callback completes, MATLAB then resumes executing the running callback.
Note
Callback interruption and execution behave differently in these situations:
If the interrupting callback is a
DeleteFcn
,CloseRequestFcn
, orSizeChangedFcn
callback, then the interruption occurs regardless of theInterruptible
property value.If the running callback is currently executing the
waitfor
function, then the interruption occurs regardless of theInterruptible
property value.If the interrupting callback is owned by a
Timer
object, then the callback executes according to schedule regardless of theInterruptible
property value.
BusyAction
— Callback queuing
'queue'
(default) | 'cancel'
Callback queuing, specified as 'queue'
or 'cancel'
. The BusyAction
property determines how MATLAB handles the execution of interrupting callbacks. There are two callback states to consider:
The running callback is the currently executing callback.
The interrupting callback is a callback that tries to interrupt the running callback.
The BusyAction
property determines callback queuing behavior only
when both of these conditions are met:
Under these conditions, the BusyAction
property of the
object that owns the interrupting callback determines how MATLAB handles the interrupting callback. These are possible values of the
BusyAction
property:
'queue'
— Puts the interrupting callback in a queue to be processed after the running callback finishes execution.'cancel'
— Does not execute the interrupting callback.
BeingDeleted
— Deletion status
on/off logical value
This property is read-only.
Deletion status, returned as an on/off logical value of type matlab.lang.OnOffSwitchState
.
MATLAB sets the BeingDeleted
property to
'on'
when the DeleteFcn
callback begins
execution. The BeingDeleted
property remains set to
'on'
until the component object no longer exists.
Check the value of the BeingDeleted
property to verify that the object is not about to be deleted before querying or modifying it.
Parent/Child
Parent
— Parent container
Figure
object (default) | Panel
object | Tab
object | ButtonGroup
object | GridLayout
object
Parent container, specified as a Figure
object
created using the uifigure
function, or one of its child
containers: Tab
, Panel
, ButtonGroup
, or GridLayout
. If no container is specified, MATLAB calls the uifigure
function to create a new Figure
object that serves as the parent container.
HandleVisibility
— Visibility of object handle
'on'
(default) | 'off'
| 'callback'
Visibility of the object handle in the Children
property of the
parent, specified as one of these values:
'on'
— Object handle is always visible.'off'
— Object handle is invisible at all times. This option is useful for preventing unintended changes by another function. Set theHandleVisibility
to'off'
to temporarily hide the handle during the execution of that function.'callback'
— Object handle is visible from within callbacks or functions invoked by callbacks, but not from within functions invoked from the command line. This option blocks access to the object at the command line, but permits callback functions to access it.
If the object is not listed in the Children
property of the
parent, then functions that obtain object handles by searching the object
hierarchy or querying handle properties cannot return it. Examples of such
functions include the get
, findobj
, gca
, gcf
, gco
, newplot
, cla
, clf
, and close
functions.
Hidden object handles are still valid. Set the root
ShowHiddenHandles
property to 'on'
to list all object handles regardless of their
HandleVisibility
property setting.
Identifiers
Type
— Type of graphics object
'uisimcontrol'
This property is read-only.
Type of graphics object, returned as 'uisimcontrol'
.
Tag
— Object identifier
''
(default) | character vector | string scalar
Object identifier, specified as a character vector or string scalar. You can specify a unique Tag
value to serve as an identifier for an object. When you need access to the object elsewhere in your code, you can use the findobj
function to search for the object based on the Tag
value.
UserData
— User data
[]
(default) | array
User data, specified as any MATLAB array. For example, you can specify a scalar, vector, matrix, cell array, character array, table, or structure. Use this property to store arbitrary data on an object.
If you are working in App Designer, create public or private properties in the app to share data instead of using the UserData
property. For more information, see Share Data Within App Designer Apps.
