check state of radiobuttons from start-button

Hi everybody,

I'm building a GUI for model control with three radiobuttons to select the run-mode. Now i want to write an if-statement in the onpress code of the start button where it is checked if one of the radiobuttons is selected. Is there a way to get the check-state of the radiobuttons in that if statement? I tried with getchecked() but either this doesn't work or I just couldn't find out the right syntax.

Thanks a lot for help!

Hello Eike,

I have used a similar feature and I will try to explain what I have done. I created a numeric label "RunMode" on a control object that was part of my model. This label can have the value 1, 2 or 3 depending on what radio button was selected.
On each radio button i used the hotlinkx attribute.
In the hotlinkx attribute i added code such as:

int MyValue = 1; // for the first radiobutton
if( eventdata == 0 ) // this is when the gui opens
{

if( getalbelnum( ControlObject, "RunMode" ) == MyValue )
{

setchecked( c, 1 );

}

}
else // this is when the apply or ok button is pressed
{

setlabelnum( ControlObject, "RunMode", MyValue );

}

Furthermore I added an OnPress attribute to each radio button with the code:
applylinks( c ), this will cause the 'else' part to be executed from the hotlinkx code.

Hope this helps you solve your problem.
