[SOLVED] Change the label (name ) of a pushbutton in Motif at run time.

Hi,

I have a question. How do I change a button's name in Motif linux at run time.

For example:

I want a pushbutton to say "Run" when the apllication not running, and when I click on the "Run" button, the application runs and the button now says "Stop" and when I click on the "Stop" button, the application stops.

This is sort of like a toggle button.

Your input would be greatly appreciated.

Thank you
H Davis.

Assuming you have a callback associated with the button, something like this could be employed:

Code:

void startAndStopCB(Widget w, XtPointer clientData, XtPointer callData)
{
    static int i = 0;
    char* label = ((i ^= 1) ? "Stop" : "Run");

    XtVaSetValues(w, XmNlabelString, XmStringCreateLtoR(label, XmFONTLIST_DEFAULT_TAG), NULL);

    //...
}
