Create push tool in toolbar
creates a push tool in the
toolbar of the current figure and returns the
pt = uipushtool
The current figure must be one created with the
figure function. If
the current figure does not have a child toolbar, then MATLAB® creates one in the current figure to serve as the parent. If a figure created
figure function does not exist, then MATLAB creates one and calls the
uitoolbar function to create a
toolbar to serve as the parent.
Push tools behave like push buttons. When you click them, they appear to depress until you release the mouse button.
Create a UI figure by calling the
uifigure function. Create a
toolbar in the UI figure.
fig = uifigure; tb = uitoolbar(fig);
Add a push tool to the toolbar. The push tool displays the default icon.
pt = uipushtool(tb);
Add an icon to the push tool by setting the
Icon property value
to the image file
pt.Icon = fullfile(matlabroot,'toolbox','matlab','icons','greencircleicon.gif');
Create a figure by calling the
figure function. Add a toolbar
to the figure. It appears below the default figure toolbar.
f = figure; tb = uitoolbar(f);
Create a push tool in the toolbar. Read a new icon from the indexed image file,
matlabicon.gif. Convert the indexed image to an RGB truecolor image
array. Add the icon to the push tool by setting the
CData property to
the truecolor image
pt = uipushtool(tb); [img,map] = imread(fullfile(matlabroot,... 'toolbox','matlab','icons','matlabicon.gif')); ptImage = ind2rgb(img,map); pt.CData = ptImage;
Modify the default figure toolbar by adding a push tool to it.
Create a figure by calling the
f = figure;
Get a handle to the default toolbar by finding all objects of type
'uitoolbar' that are in the figure.
defaultToolbar = findall(f,'Type','uitoolbar')
defaultToolbar = Toolbar (FigureToolBar) with properties: Children: [0×0 GraphicsPlaceholder]
Create a push tool in the default toolbar. Create a 16-by-16-by-3 array of random
RGB values to be its icon. Add the icon to the push tool by setting the
CData property to this array.
pt = uipushtool(defaultToolbar); ptImage = rand(16,16,3); pt.CData = ptImage;
Create a push tool that opens the
dialog box when you click it. Change the background color of the UI figure to the color
selected from the color picker.
First, create a program file called
the program file:
Create a UI figure.
Create a toolbar in the UI figure.
Create a push tool in the toolbar.
Add an appropriate icon to the push tool by setting the
property value to the full file path to
Create a tooltip for the push tool.
ClickedCallback property to a function handle that
references a callback function called
Create a callback function called
colorToolClicked. In it,
uisetcolor function so that a color picker dialog opens
when you click the push tool in the toolbar. Set the default color of the color
picker to be the color of the UI figure and specify the title of the color picker as
'Select UI Figure Color'. Make the UI figure the current figure
so that it displays on top of all other figures.
function colorPickerPushTool fig = uifigure('Position',[350 500 400 300]); tb = uitoolbar(fig); pt = uipushtool(tb); pt.Icon = fullfile(matlabroot,'toolbox','matlab','icons','paintbrush.gif'); pt.Tooltip = 'Change UI Figure Color'; pt.ClickedCallback = @colorToolClicked; function colorToolClicked(src,event) c = uisetcolor(fig,'Select UI Figure Color'); figure(fig) end end
colorPickerPushTool. Click the push tool to open the color
picker. Then, select a color to change the background color of the UI figure.
parent— Parent toolbar
Parent toolbar, specified as a
Toolbar object. Use this property
to specify the parent toolbar when creating a push tool or to move an existing tool to a
different tool bar.
If a parent toolbar is not specified, then MATLAB creates a push tool in the toolbar of the current figure. The current
figure must be one created with the
figure function. If the current
figure does not have a child toolbar, then MATLAB creates one in the current figure to serve as the parent. MATLAB does not create the push tool in the default figure tool bar.
If a figure created with the
figure function does not exist,
then MATLAB creates one and calls the
uitoolbar function to
create a toolbar that serves as the parent.
If you add multiple push tools or toggle tools to a toolbar, they are added left to right, in the order that they are created.
comma-separated pairs of

The properties listed here are only a subset. For a complete list, see PushTool Properties.
Icon— Icon source or file
''(default) | character vector | string scalar |
n-by-3 truecolor image array
Icon source or file, specified as a character vector, string scalar, or an
n-by-3 truecolor image array. If you
specify a character vector or string scalar, it can be an image file name on the
MATLAB path or a full path to an image file. If you plan to share your app with
others, put the image file on the MATLAB path to facilitate app packaging. Supported image formats include JPEG,
PNG, GIF, and SVG.
If you specify an
n-by-3 array, it is
interpreted as a truecolor image array. For more information about truecolor image
arrays, see Image Types.
If the image you specify is larger than 16-by-16 pixels, then the
Icon property scales the image down so that the entire image fits within the tool. If the image you specify is smaller than 16-by-16 pixels, it is not scaled up to fit the available space.
Icon property is supported only in App Designer and
uifigure-based apps. If the
CData properties are both set, then the
CData property is ignored.
'icon.png' specifies an image file on the MATLAB path.
'C:\Documents\icon.png' specifies a full path to an image file.
Toolbar objects (and their child
ToggleTool objects) do not appear in figures whose
WindowStyle property is
'modal'. If a figure containing a toolbar child has its
WindowStyle changed to
'modal', the toolbar child
still exists in the
Children property of the figure.
However, the toolbar does not appear while
WindowStyle is set to
