The uicontextmenu() function is supposed to take a parent handle as input, but when querying a resultant's object's parent, I always get the top level figure. What am I missing?
Example to illustrate:
hFig = figure;
ax = axes;
hXLab = xlabel(ax,'XLABELSTRING');
hFig.UIContextMenu = uicontextmenu;
ax.UIContextMenu = uicontextmenu;
hXLab.UIContextMenu = uicontextmenu;
for i = 1:4
uimenu(hFig.UIContextMenu , 'Label',...
sprintf('fig item %d',i) ...
uimenu(ax.UIContextMenu , 'Label',...
sprintf('ax item %d',i) ...
uimenu(hXLab.UIContextMenu , 'Label',...
sprintf('xLabel item %d',i) ...
I would expect the first line to return the figure handle, the second line to return the axes handle, and the third line to return the axis label handle, but they all return the figure handle.
Why I want to do this: if there are multiple axes in my GUI, it would be nice to write a general purpose callback for a uicontextmenu object associated with an axes to operate on its parent axes.
One way I can think of to achieve this is to hard-code the intended parent's handle into the uicontextmenu object's UserData property, but that seems inelegant...
