GUIDE-edit text

Hi,

I have edit text in guide. When I write anything to edit, then I want enable pushbutton. So, how can I do this?

. . . set(handles.pushbutton, 'enable','on');

function exampleEditEnable
%Build stuff
hFig = figure;
hBut = uicontrol('style','push','units','norm','position',[0 0 0.3 0.1],'enable','off','string','can''t touch this'); %a button
hEdit = uicontrol('style','edit','units','norm','position',[0.5 0.5 0.3 0.1],'string','edit me, I dare you!','callback',@enableButton); %an edit box

    function enableButton(varargin)
        set(hBut,'enable','on');
        set(hBut,'string','can touch this');
    end
end

To translate this into GUIDE just use handles.edit and handles.pushbutton etc.

can you help me?...maybe my code is wrong, cause it doesn't work

function edit5_Callback(hObject, eventdata, handles)

h=findobj(0,'Type','figure','Tag','figure1');

set(handles.edit5,'callback',@enableButton);

function enableButton(varargin)

set(handles.pushbutton4,'enable','on');

end

set(h,'UserData',UserData);

guidata(hObject, handles);

[Sean de Wolski]

way too much effort, if edit5 is the ditbox and pushbutton4 is the pushbutton, all you need is:

function edit5_Callback(hObject,eventdata,handles)

set(handles.pushbutton4,'enable','on');

Tada!

[john]

thank you man,,,,,,so easy :-)

[john]

So but I have to press ENTER to make pushbutton4 to enable on. So, how can I enable on, when I insert mouse cursor into edit5?

[Sean de Wolski]

Add a 'preset' listener to the 'selected' property of the edit box.

doc addlistener

[john]

I doesn't have 'selected' in property inspector ....

you would put that code that you wrote in the edittext callback function.
