MATLAB: How to get the figure window handle containing a given UI component

ancestoraxeschart;componentcontainingfigureMATLABparentplot

I have some UI component (e.g. axes, chart, line) handle and I want to find the handle to the figure window containing this component. How can I do this?

Best Answer

Use the "ancestor" function. Assuming the UI component is called "obj", you can use the following code to get the figure handle:

figureHandle = ancestor(obj, 'figure');

Note that this function will return an empty array if the component does not belong to a figure window.

Additionally, you may check parent of the UI component "obj.Parent".

I had encountered the same issue. One option would be to modify the pcshow function Modify the line around Line 108

% Get the current figure handle
hFigure = get(currentAxes,'Parent');

htmp = currentAxes;
while true
    hFigure = get(htmp, 'Parent');
    htmp = hFigure;   
    if isa(hFigure, 'matlab.ui.Figure')
        break;
    end     
end

Hope this helps.
