8 Programming a GUIDE GUI

2 Create callbacks for the two push buttons, and place the follow ing line of

code in each of them.

set(gcbf,'Position',[420 520 150 190])

This resets the GUI to its initial size, so you c an experiment with resizing

it manually.

3 In the Property Inspector, set the Unit s of the panel and the two buttons to

normalized.AlsosetthefontSiz e of both buttons to 10. Make sure that

the

fontUnits property for both buttons is set to p oints.

4 Create a ResizeFcn callback for the panel by Clicking the pencil icon for the

ResizeFcn in the Property Inspector and insert the following code into it.

function uipane l1_R esizeFcn(hObject, e vent data, handles)

set(hObject,'Units','Points') % Was normalized

panelSizePts = get(hObject,'Position'); % Now in points

panelHeight = panelSizePts(4);

set(hObject,'Units','normalized'); % Now normalized again

% Keep fontsize in constant ratio to heigh t of panel

newFontSize = 10 * panelHeight / 115; % Calculated in points

buttons = get(hObject,'Children ');
