I am creating an simple gtkmm program that han an Gtk::Entry inside an Gtk::Frame. I want the frame label to go red when the text in the entry is changed.

I already know how to deal with the signals. I just need to know whan method shoud I call in order to change the color of the frame label.

Thank you!

Hello,

If all you want to do is set the text of the label on the frame to red then, my thought is to do some thing like this.

Code:

...
  Gtk::Label * frame_label = dynamic_cast<Gtk::Label *>(frame_widget.get_label_widget());
  if (frame_label)
    frame_label->set_markup("<span foreground="red">Red Text</span>");
...

Note that I have not tested this

As an additional note do not depend on the colour of an object to give all the feedback to the user. In this case the user may have colour blindness which affects red so would not see any visible change.

Hello

Thank you for your answer. It didn't work quite like that because get_label returns a const, but it made me find out that I could set the label widget directly using set_label_widget, which solved my problem.

Also, thank you for the tip about the color blindness. Now it also adds an asterisk in the end of the label when the entry is changed.

Thank you! =D

Sorry,

get_label() should have read get_label_widget().
