I'm using a selector trigger to bring up a modal editing form (to edit
the string in the trigger), but when the modal form goes away, the size
of the selector trigger remains the same, even though the text has
correctly changed. Going to another form then back again corrects the
problem, so I know the selector trigger has "the right stuff." I just
haven't figured out how to ensure that it resizes correctly.
I've tried endless combinations of Hiding/Showing the control, saving or
not saving the bits behind the modal form, etc., and nothing seems to
work.
The code looks basically as below (names changed to protect the
innocent): note that I have a globally allocated string for the selector
trigger label, since it will change often. It's initially attached to the
control when I initialize the form, then retrieved for modification here.
Again, the modified text shows up when the modal editor goes away, but
the auto-sizing feature of the selector trigger isn't getting invoked
(text is clipped if it's longer than before, etc.).
static void EditThang( ControlPtr controlPtr )
{
FormPtr previousForm, editorForm;
UInt16 hitButton = EditorCancelButton;
char *str; // pointer to the global string for the selector trigger
// Get the current form, init and activate the editor form
previousForm = FrmGetActiveForm();
editorForm = FrmInitForm( EditorForm );
FrmSetActiveForm( editorForm );
// Get the global string we're dealing with
str = (char *)CtlGetLabel( controlPtr );
// Set the string in the editing field in the modal form
if( SetFieldTextFromStr( EditorField, str) )
{
// Text successfully set, so do the dialog
FrmEraseForm( previousForm ); // We're not saving bits, so erase
underneath first
hitButton = FrmDoDialog( editorForm );
}
// If OK is hit, change the label in the control
if( hitButton == EditorOKButton )
{
GetStrFromFieldText( EditorField, str);
CtlSetLabel( controlPtr, str ); // necessary? It's the same string,
but
// this should notify the control that
it changed
}
// Restore previous form and delete the editor
if( previousForm )
{
FrmSetActiveForm( previousForm );
FrmDrawForm( previousForm );
}
FrmDeleteForm( editorForm );
}
Any help appreciated.
