Hello Everybody, I need your Help. I build a GUI and I want to activate or deactivate a Edit Text Box with the Help of a Checkbox. The following is my Code for this Problem:
WN = get(handles.White_Noise,'Enable');
if WN == 'on'
set(handles.WN_per,'enable','on');
set_param('Physikalisches_Modell/Noise_Enable','Value',num2str(1));
else WN == 'off'
set(handles.WN_per,'enable','off');
set_param('Physikalisches_Modell/Noise_Enable','Value',num2str(0));
WN_per = 0;
end
White_Noise is the Checkbox, WN_per is the Edit Text. The Part, to activate the Edit Text Box works perfectly fine, but i cannot deactivate it with pressing it again.
There was another Topic for this Problem, where the User hat a similar Code and it worked, when he Startet the GUI with the Command Window. Unfortunatly, this is not the Solution.
Can anyone help me?
Tanks, Jan

For both conditionals, instead of
if WN == 'on'
use
if strcmp(WN, 'on')
See comments below. You want to condition on the 'Value' property, not the 'Enable'.

Thank you very much! Now that I know the Answer, its pretty obvious, that I mistake the handles I used.
I want to add, that the 'Value' gives a number, 0 or 1. So in the if-condition, i set
if WN == 1
....
else if WN == 0
....
end

The value property is a logical. So all you need is
if WN
if ~WN
