uicontextmenu

Syntax

h = uicontextmenu()

h = uicontextmenu(property, value, ...)

h = uicontextmenu(parent, property, value, ...)

Inputs

parent

Handle of a figure, uitab, or uicontrol objects of styles 'pushbutton', 'togglebutton', and 'text'.

Type: double | integer

property, value

'createfcn'

Function that is triggered when h is created. If value is a function handle, it must be a function that takes at least two arguments. The first argument is the handle of the uicontrol. The second argument is the event data to the uicontrol, which is ignored for createfcn. If value is a string, it must represent a function handle or a function name. If value is a cell, it must contain the function name/function handle in the first cell element and parameters to pass to callback function in the additional elements. After it is executed, createfcn cannot be interrupted.

Type: cell | functionhandle | string

'deletefcn'

Function that is triggered when h is deleted. If value is a function handle, it must be a function that takes at least two arguments. The first argument is the handle of the uicontrol. The second argument is the event data to the uicontrol, which is ignored for createfcn. If value is a string, it must represent a function handle or a function name. If value is a cell, it must contain the function name/function handle in the first cell element and parameters to pass to callback function in the additional elements. After it is executed, createfcn cannot be interrupted.

Examples

% Callback for menu1
function outfunc1 = func1(h,callstate)
    disp('Menu item 1 callback')
end

% Callback for menu2
function outfunc2 = func2(h,callstate,argument1,argument2)
    disp('Menu item 2 callback')
end

f = figure;
c = uicontextmenu(f);

% Creates individual context menu items
menu1 = uicontextmenuitem('parent', c, 'label', 'Do something', 'callback', '@func1');
menu2 = uicontextmenuitem(c, 'label', 'Do something else', 'callback', {@func2, 'foo', 1});

% Callback for menu1
function outfunc1 = func1(h,callstate)
    disp('Menu 1 callback')
end

% Callback for menu2
function outfunc2 = func2(h,callstate,argument1,argument2)
    disp('Menu 2 callback')
end

f = figure;
button = uicontrol('style', 'pushbutton', 'string', 'Test');
c = uicontextmenu(button);

% Creates individual context menu items
menu1 = uicontextmenuitem('parent', c, 'label', 'Do something', 'callback', '@func1');
menu2 = uicontextmenuitem(c, 'label', 'Do something else', 'callback', {@func2, 'foo', 1});
