Is it SpinButton? Entry? Menu? and so on... Please give us the Widget type or at least screen shot. But "control" is a Widget, you can use the "hide()" method, or set the visible property into false.
> I need to catch > double-mouse-click event and change one control to another and so one. > Can somebody help me? button_press_event in Widget is what you need. There is an Gdk.EventButton parameter, usually called "e" in Vala: http://valadoc.org/#!api=gdk-3.0/Gdk.EventButton It contains all information you need, including what type of click it was. This is an example method for this event: bool signal_handler_event(Widget widget, Gdk.EventButton e) { if (e.type==EventButton.2BUTTON_PRESS) { // Something } return FALSE; }Yours Tal > Date: Tue, 14 Aug 2012 16:59:19 +0600 > Subject: Re: [Vala] How can I get information about vala & gtk? > From: [email protected] > To: [email protected] > > Thanks, it's really nice, but I have a few tasks already and can't > find, how to solve it. > For eample: I need to make some control invisible, I need to catch > double-mouse-click event and change one control to another and so one. > Can somebody help me? > > 2012/8/14 Tal Hadad <[email protected]>: > > > > I'll give you the magic trick: > > Look at the examples and when you find some example interesting, > > start to twick the code. > > Only experience can truly teach you. > > It works for me, hope it will work for you. > > > > See for example, the GTK example: > > https://live.gnome.org/Vala/GTKSample > > I'll give you homework if you want with this examples: > > * Basic Sample: After the first click, when the text is changed into > > "Thank you", the next click will make the window to exit. > > * Synchronizing Widgets: Add a nice restore default button with blue > > background. > > * Creating a Dialog: Add a button with clear the text in the entry. > > > > I don't tell you how to do it, you'll have to search the web. > > Do what ever you want to do with them.
