How To change label button

[lightcalamar]

Hello.

I have one problem. Not change label button after touch. My code;

     GD.Tag(105);
     GD.cmd_fgcolor(0x000000);
     GD.ColorRGB(0xff8000);
     GD.cmd_button(280, 180, 110, 30, 28, 0,  "STEREO");  
     if (GD.inputs.tag==105){
         radio.setMono(true);
         GD.cmd_fgcolor(0x000000);
         GD.cmd_bgcolor(0x300030);
         GD.ColorRGB(0x00ff00);  
         GD.ClearTag(105);
         GD.cmd_button(280, 180, 110, 30, 28, 0,  "MONO");
       }  
When you press MONO but exit STEREO again, how do you exit MONO when you press?
Regards

You need some kind of state variable in your program.

Maybe something like this:


     static int ismono = 1;

     if (GD.inputs.tag != 105)
         GD.Tag(105);
     GD.cmd_fgcolor(0x000000);
     GD.cmd_bgcolor(0x300030);
     char *label;
     if (ismono) {
         GD.ColorRGB(0x00ff00);  
         label = "MONO";
     } else {
         GD.ColorRGB(0xff8000);
         label = "STEREO";
     }
     GD.cmd_button(280, 180, 110, 30, 28, 0,  label);

     if (GD.inputs.tag == 105) {
         ismono = !ismono;
         radio.setMono(ismono);
     }
