creating App design control buttons programmically
显示 更早的评论
I'm trying to create an app design that would read an xls spreadsheet and create a new button if someone was to go in and add an extra column of data.
Initially I thought of doing a "for loop" statement, but I don't know the code that would generate a new button for how ever many columns that are added in the spreadsheet.

I have two ideas.
- Idea 1: Creates buttons from the first but make the button invislble in a startup function.
% Code that executes after component creation
function startupFcn(app)
app.Button.Visible = 'off';
end
Then, make the button visible at the timing when you want.
app.Button.Visible = 'on';
I think this approach is bettter than idea 2 because you can control the layout and
- Idea 2: Create a button programmically
You can create a button by "uibutton". But you need to locate a new button properly by setting Postion.
The following example will create a button 120px right to the existing Button1.
% Button pushed function: Button
function ButtonPushed(app, event)
pos = app.Button.Position;
app.Button1 = uibutton(app.UIFigure, 'push');
app.Button1.Position = [pos(1)+120 pos(2) pos(3) pos(4)];
app.Button1.ButtonPushedFcn = {@mybuttondown,app};
% Button push function for a new button
function mybuttondown(src,eve,app)
msgbox('Hello')
end
end
