That depends on what you mean. You can find out if it has been shown or hidden programmatically by calling GTK_WIDGET_VISIBLE() (or from gtk+-2.18, gtk_widget_get_visible()). However, that will not tell you whether the widget is obscured or iconified (that is, whether it is actually visible on the desktop). You will need to track notify events and state events to do that.

On 10 May 2010 11:22, Lothar Scholz wrote: > And what does "mapped" mean? Here's my understanding of what happens when you show a window. I'm sure I've made some errors and reality is far more complex :( 1) You build the contents with gtk_label_new() and friends. A window/widget in this state is !_get_visible(). When you want to show it, you call gtk_widget_show(). After calling _show(), _get_visible() will start returning TRUE (I think this is correct?), but your window is a long way from actually being visible to the user. Most of the rest of the process happens asynchronously (except for resource allocation, I think) over the next few milliseconds with a lot of chit-chat back and forth between your program and the underlying window system. 2) First your window and widget are realized. This is the process of allocating real window system resources (eg. windows, pixmaps, colourmaps and so on) to the components of the window. You can implement a _realize method if you want to be part of this process. 3) Next everything is configured. This is computing the layout of widgets within your window. You can implement a _configure_event method to be part of this process. Erm, I think this happens here, perhaps it's actually after map. 4) Now things are mapped. This is the process of asking the window system to display the windows on the screen. map/unmap are a good pair of events to look for if you want to be aware of window or widget visibility at the lowest level. 5) Finally expose events come in from the window system, are routed to your widgets, and cause drawing of the screen to take place. This can be a long time (many milliseconds) after your original _show() call. John ___ gtk-list mailing list gtk-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-list
gtk_toggle_button_get_active() error in clicked event?
Hi!
void on_element_clicked (GtkButton *button, gpointer user_data) {
if (gtk_toggle_button_get_active(GTK_TOGGLE_BUTTON(button))) {
g_warning("good");
}
else {
g_warning("wrong");
}
}
If clicked element is toggled, output: "good". But if clicked element
is not toggled, output: "wrong" and "good". Why running twice? This is
GTK+ bug?

One interesting thing you will find when you do that is that calling hide on the window will cause GTK_WIDGET_VISIBLE() to return false but will NOT trigger a window visibility event. And it will absolutely not tell you whether the window is obscured or not. Chris ___ gtk-list mailing list gtk-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-list

I already responded to your query here[1], but you failed to provide
any additional information about it. So I'm asking again, what exactly
are you doing when user clicks on toggle button? Are you performing
any kind of checks and set the state of toggle button according to the
result?

Re: gtk_toggle_button_get_active() error in clicked event?
Hi. I quickly glimpsed at your code and now I see where you're having troubles. When you click unselected radio button, your GtkButton::clicked signal handler is called twice: first time signal is emitted in order to deselect currently active radio button and second time signal is emitted to select new radio button. You need to keep in mind that GtkButton::clicked signal is an action signal, which means that it can be emitted by application without button being actually pressed.

problem with compiling different C files with a global structure
Hello,
Though this might not be the place for this type of query, this problem I'm
giving here is a simplest scale version of a problem when I am trying to
split up a large gtk source code of mine.
I'm trying to compile a program with 3 diff C files.
*main.c*
*call.c*
*global.c*
I want to declare a global structure variable and assign a value to it's
content in *main.c*
then I will call another function (declared at *call.c* ) to print the
global variable.
I have a structure definition in *global.c* which I have declared as extern
in the common header file *head.h* through another header file *global.h*
Program is not compiling.
Am I missing some points here?

Re: problem with compiling different C files with a global structure
Hi Debmalya, Do not use automatic initialisation in variables with the extern attribute. Initialise a.data by assignment in main(). This is not the whole story but then your example code is not exactly what you tried to compile! (calling cal() in main() ) but defining call in call.c never-the-less you get the idea) Leon On 11 May 2010 07:04, Debmalya Sinha wrote: > Hello, > > Though this might not be the place for this type of query, this problem I'm > giving here is a simplest scale version of a problem when I am trying to > split up a large gtk source code of mine. > > > I'm trying to compile a program with 3 diff C files. > *main.c* > *call.c* > *global.c* > > I want to declare a global structure variable and assign a value to it's > content in *main.c* > then I will call another function (declared at *call.c* ) to print the > global variable. > > I have a structure definition in *global.c* which I have declared as > extern in the common header file *head.h* through another header file * > global.h* > > Program is not compiling. > > Am I missing some points here? > > > -- > Regards, > > Debmalya Sinha > > Research Scientist, > MS(R) student, > Computer Science and Engineering > IIT Kharagpur > > > Fedora Ambassador > Chandannagar > India. > > sunnywizard.googlepages.com > > > GPG Key : 6E2BD51B > Keyserver : http://pgp.mit.edu > > ___ > gtk-list mailing list > gtk-list@gnome.org > http://mail.gnome.org/mailman/listinfo/gtk-list > > ___ gtk-list mailing list gtk-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-list

Therefore, applications can be prepared for porting to GTK+ 3 by making sure that they build with -DGTK_DISABLE_DEPRECATED and -DGSEAL_ENABLE. * Bugs should be reported to http://bugzilla.gnome.org. What is GTK+ GTK+ is a multi-platform toolkit for creating graphical user interfaces. Offering a complete set of widgets, GTK+ is suitable for projects ranging from small one-off tools to complete application suites. GTK+ has been designed from the ground up to support a range of languages, not only C/C++. Using GTK+ from languages such as Perl and Python (especially in combination with the Glade GUI builder) provides an effective method of rapid application development. GTK+ is free software and part of the GNU Project.
