I'd like to have a progress dialog box be contained inside of a GUI axis, instead of in an external figure tab.
A GUI axis is a uifigure, and since one of the inputs for 'uiprogressdlg' is a figure, I thought the following would work:
% app.prog is the uifigure in question
% app.prog = uiaxes(app.UIFigure);
uiprogressdlg(app.prog,'Title','Please Wait','Message','any message.....');
However, doing this does not work, and I get the following error message:
% Error using matlab.ui.dialog.ProgressDialog (line 44)
% Invalid or deleted figure handle. First argument must be a valid figure handle
Does anyone have any idea why this would not work, maybe I am missing something very simple.
Appreciate anyone's help!

According to the documentation, uiprogressdlg() accepts figure created from uifigure() as an argument.
But according to your code you are trying to pass a UIAxes object as an argument hence you are receiving the error "Invalid or deleted figure handle". So you can use a figure handle as an argument to uiprogressdlg().
The appearance and behaviour of progress dialog can be customized by changing its properties.
Also, waitbar() provides a similar functionality if your interested.
