Programmatically add AppDesigner uicontrol
5 ビュー (過去 30 日間)
I have a CSV file with a list of m-files, and I want an AppDesigner GUI to have 1 button per m-file. Let's pretend all each button does is call "edit(mfile#)" for the appropriate number. Since all controls are explicit properties of the app, it gets very angry trying to create controls inside the startupFcn. It also does not seem to like using the GraphicsPlaceholder to pack multiple controls into a single app property.
I'm using a workaround that is effective for my current need, but might not be next time. I know the maximum number of m-files, and declaring an app property as a button doesn't actually create the button. So, I manually create the maximum properties, then fill as I read the CSV file.
Any other thoughts or suggestions?

fig = uifigure;
panel = uipanel(fig,'Position',[1 1 500 500]);
bg = uibuttongroup(panel,'Position', [50 50 100 500]);
n = 10;
g = gobjects(n,1);
for ii = 1:n
uibutton('Parent',bg,'Position',[10 ii*30 50 30])

Instead of generating buttons, I think it would be better to populate a Drop Down with the names of the files, and open them that way, either on a selection changed callback, or with a separate button that opens the file based on the current selected value.
Generating buttons on the fly is generally never done for a reason.
