Hi everyone. What code to use under a push button if I want to enable or disable an "edit text" when that push button is clicked? Thank you very much.

在 MATLAB Online 中打开

set(handles.TheTextBox, 'enable', 'off')

Note: there is also 'disable' instead of 'off'. When it is 'disable', the text is still there and still readable and scrollable, but cannot be changed.

It's actually 'inactive', not 'disable', instead of 'off'. Maybe they changed it. But I see no significant difference between the two other than 'off' greys out the background while 'inactive' leaves it white. But neither one of them allow for selecting/highlighting.

No, they didn't change it, the "Enable" property of an edit box has three modes: on, off or inactive. The user can only modify it contents when Enable = on. Yea, off greys it out while inactive leaves it white. I noticed if you use an edit box as a memo box with many lines of text (and vertical scroll bar), you can't use the vertical scroll bar if the edit box is off, but can if its inactive.
