ButtonDownFcn for a uicontrol will execute on left-click if the uicontrol is not enabled (off or inactive.), so, to use ButtonDwnFcn function my edit text is inactive initially. then when i want to use it to insert a value, i have to click two times. the first time to enable the edit text and the second time to allow to type a value. can i resolve in one single step using only one click?
