MATLAB: Do MATLAB UIControls not redraw on Windows 2000

ghostMATLABuicontrol

In MATLAB 6.5 (R13) running under Windows 2000, a GUI having many listboxes can sometime be drawn incorrectly. The UIControls (listboxes) keep the background of the screen that was in that occupied position before the window was raised.

This issue has been fixed in MATLAB 7.0 (R14).

This is an issue in the way that MATLAB 6.5 (R13) figures handle popup UIControls on Windows 2000.

This is a limitation in MATLAB 6.5 (R13) with the number of listboxes allowed in a figure.

To work around the problem, try deleting the object in GUIDE and recreating it. Some customers have reported that this was successful, but it is not guaranteed to resolve the problem.

Another workaround you can try is to place a frame behind all other objects. If you have axes in your GUI, see the related solutions section at the bottom of this page.

Note that if you move the figure off the monitor and bring it back, the UICONTROLs show up correctly. However, changing focus from and to the window again will cause the problem again.

This issue has been reported to our development staff to be addressed in a future release of MATLAB.

One possible workaround is to capture an image of the GUI using GETFRAME and then print to an image file using IMWRITE. You can then print the GUI from another application. For example:

h = figure;
surf(peaks);
ui = uicontrol('Style', 'Pushbutton', 'String', 'Text');
[X,map] = getframe(h);
imwrite(X,map,'test.jpg');
