Hi, I have a gui with an edit text box and few buttons.... like a calculator...
the edit text box receives input from the keyboard and from the pushbuttons... now the problem is after clicking the pushbuttons, i have to return focus to the edit box manually through the mouse. But i want the cursor to be returned to the edit text box automatically so that i can immediately continue typing after pressing the pushbutton.... can you help?

You can call uicontrol() and pass in just the handle of the edit box in order to return focus to the edit box.
However, when you do that, the entire string of the box might be highlighted, so typing anything at that point might replace everything in the edit box.
If you need to position the cursor to a particular location in the edit box, then you are going to need to go in at the Java level and access the properties of the underlying Java Swing control.
