Re: Accelerators for GtkNotebook to switch between pages
Oh no sorry. It not working. I had just defined the t
accelerator in the activate function of the app.
If I change it to e.g. b the accelerator doesn't work.

Re: Accelerators for GtkNotebook to switch between pages
Hi infirit,
crazy. I rebuilt the relevant parts in a demo app and there it's working
as expected. *argh*.
For completeness here's what I mean.
The code that creates my GtkNotebook:
/* notebook */
notebook = gtk_notebook_new();
gtk_notebook_set_tab_pos(GTK_NOTEBOOK(notebook), GTK_POS_TOP);
gtk_notebook_set_scrollable(GTK_NOTEBOOK(notebook), TRUE);
gtk_container_add(GTK_CONTAINER(frame), notebook);
/* notebook page 1 */
label = gtk_label_new("Tab1");
gtk_widget_show(label);
page = gtk_frame_new("Content1");
gtk_widget_show(page);
gtk_notebook_append_page(GTK_NOTEBOOK(notebook), page, label);
/* notebook page 2 */
label = gtk_label_new("Tab2");
gtk_widget_show(label);
page = gtk_frame_new("Content2");
gtk_widget_show(page);
gtk_notebook_append_page(GTK_NOTEBOOK(notebook), page, label);
create_tab_menu(notebook);
And this is the content of the create_tab_menu() function to create the
context menu of the tab, that actually contains the action to be
triggered by the accelerator:
void create_tab_menu(GtkWidget *notebook)
{
GtkWidget *menu;
GtkBuilder *builder;
GSimpleActionGroup *actiongroup;
int i;
struct accel_map {
char *action;
const char * const accel[2];
};
/* define actions */
static GActionEntry tab_actions[] = {
{"test_action", test_cb, NULL, NULL, NULL, {}}
};
/* define accelerators */
static struct accel_map tab_accels[] = {
{"tab.test_action", {"t", NULL}}
};
/* define menu structure */
builder = gtk_builder_new();
gtk_builder_add_from_string(builder,
""
" "
" "
" "
" Test Action"
" tab.test_action"
" weather-clear-symbolic"
" "
" "
" "
"", -1, NULL);
/* create actiongroup and map actions */
actiongroup = g_simple_action_group_new();
g_action_map_add_action_entries(G_ACTION_MAP(actiongroup),
tab_actions,
G_N_ELEMENTS(tab_actions), NULL);
/* map accelerators to actions */
for (i = 0; i < G_N_ELEMENTS(tab_accels); i++)
gtk_application_set_accels_for_action(GTK_APPLICATION(app),
tab_accels[i].action, tab_accels[i].accel);
/* create new GtkMenu from GtkBuilder */
menu =
gtk_menu_new_from_model(G_MENU_MODEL(gtk_builder_get_object(builder,
"tab-menu")));
/* insert action group into menu */
gtk_widget_insert_action_group(menu, "tab",
G_ACTION_GROUP(actiongroup));
/* connect tab menu to right-click handler of notebook */
g_signal_connect(G_OBJECT(notebook), "button-press-event",
G_CALLBACK(context_cb), menu);
g_object_unref(builder);
}
And for completeness the right-click handler:
gboolean context_cb(GtkWidget *notebook, GdkEventButton *event,
gpointer data)
{
(void) notebook;
if (event->button == 3) {
gtk_menu_popup_at_pointer(GTK_MENU(data), (GdkEvent*)event);
return TRUE;
}
return FALSE;
}
However, I'm afraid I'm back on my own and just have to find where it
goes wrong in my application.
Thanks

Accelerators for GtkNotebook to switch between pages
Hi list, I'm looking for a way to switch between the pages of a GtkNotebook using e.g. Left and Right. I searched the documentation from different angels but didn't found a obvious way how to accomplish that. Does somebody have a hint for me pointing into the right direction? Thank you verymuch in advance. - Alex ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org https://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
Re: Pause and resume GtkApplication
Hi just FYI: I solved it. The trick was that within the second g_application_run(), the app menu must be attached to the application using gtk_application_set_app_menu() *before* adding the already existing _window_ using gtk_application_add_window() to the application. This way the app-menu is properly (or still) shown in the same window throughout both GtkApplication instances.

Re: Pause and resume GtkApplication
It's not really because of async execution. I just tried various gtk_window functions that trigger the "window-state-change" event. But not all of them provide the desired effect. e.g. gtk_window_maximize() reappears the app-menu. gtk_window_iconfify() not So I wonder what is the default callback function of that signal which in case of maximization does a little thing that brings back the app-menu to my window. ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org https://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
Re: Pause and resume GtkApplication
Thanks Lucky,
Good idea to create the widget right away and hide it until it's time.
However, just by accident, I got back the app-menu in the window.
Try this with the code below:
1. After I selected "Restart" simulating the pause and resume, the
app-menu disappeared.
2. Then I double-clicked the header-bar to maximise the window and the
app-menu reappeared.
3. Again double-clicked the header-bar to restore the original geometry
the app-menu is still there.
This is what I want. Question is, what happens when I double click the
header-bar and can I emulate this event in code?
I feel being just 1 grain off my goal
Thanks
-Alex

Pause and resume GtkApplication
Hi, I have an application where some things need to be setup in the UI, then some low-level routines to be executed using the setup values and then resuming the UI loop for further operation. Since I'm migrating the GTK code from GTK2/3 compatible to GNOME/GTK3, I make use of g_application_run(). However, I find no simialar way to interrupt the loop (e.g. gtk_main_quit()) and resuming the UI later (gtk_main()). The only way I found yet is to quit the application using g_application_quit() but keep the window widget, clearing the application (g_object_unref()) and creating a new application after executing the low-level routines and finally adding the still existing window widget to this new application using gtk_application_add_window(). This way I can reuse the window and avoid any flickering which is the required effect. The only caveat is, the added window is not considered being the primary instance of the second application, hence the app-menu isn't displayed. Is there any way to define a window added being the primary instance of the application or to show the app-menu (set using gtk_application_set_app_menu()) in such an non-primary window, or even a complete different approach?

GTK+ 2.24.8
GTK+ 2.24.8 is now available for download at: http://download.gnome.org/sources/gtk+/2.24/ ftp://ftp.gnome.org/pub/GNOME/sources/gtk+/2.24/ ac2325a65312922a6722a7c02a389f3f4072d79e13131485cc7b7226e2537043 gtk+-2.24.8.tar.bz2 8a3b29f667933cf52eea2db7b066723edbc80443ca9c75b7cd7cbe8c8b90b93c gtk+-2.24.8.tar.xz This is a bug fix release in the stable 2.24 series. 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. However, the licensing terms for GTK+, the GNU LGPL, allow it to be used by all developers, including those developing proprietary software, without any license fees or royalties. Overview of Changes from GTK+ 2.24.7 to 2.24.8 == * Win32 updates: Major update of the win32 backend, it now works at least as well as the old 2.16.x version that a lot of windows applications was forced to use Some particular highlights: - Tablet support (wintab) works - The MS-Windows theme works better, and is enabled by default on Windows - Pointer grabs on button press now works - Initial Window positioning is improved and now works very similarly to the X11 backend - Scrolling a window with another window overlapping it doesn't produce rendering artifacts on XP - Configure event delivery after window move or resize is much more robust, fixing a variety of rendering hangs and misbehaviours - Scrolling with synaptics touchpads work better * OS X updates: - Add Command-cursor keyboard navigation in text widgets - Fix loss of motion events after using the menu bar - Handle recursive CFRunLoops, fixing e.g. crashes when dropping files from finder - Set proper event-state values in all events * Ensure that the MOD1 modifier always means ALT, as this assumption is already used in many places in Gtk+ * Search engine backend updated to Tracker 0.12 * Bugs fixed: 84314 gdk_display_sync() and gdk_flush() 142874 use of SetWindowLong in gdkwindow-win32.c causes... 169811 configure_event and window-state-event are not... 171456 Keep Above option in Gimp broken on Win32 324254 Realizing a top-level window widget early positions... 516822 gtk_window_fullscreen does not resize correctly if... 537296 Maximizing a window larger than the screen makes... 542777 Scroll-Wheel doesn't scroll (Win) 552041 Windows' System Menu from taskbar is buggy 574935 win32: gtk_window_set_geometry_hints() has no effect... 604156 gtk_window_set_modal() freezes application completely 612359 Dialog positioning hints fail on Windows 7 631384 Images pasted from clipboard are shifted/wrapped 647460 typo in msw_style.c? 650300 Notebook tabs are incorrectly displayed with the... 658272 Port gtksearchenginetracker.c to tracker 0.11/0.12 659565 unbreak compilation on OpenBSD 661997 Gtk crashes when changing the TreeView model while ... 662633 Scheduled transaction editor crashes with gtk+-2.24.7 662670 Pressing Enter in print dialog box will not cause... 663138 iconview: layout items immediately when setting... 663182 NSImage throws an exception from _gtk_quartz_... 663543 Huge memory leak while using MS-Windows theme (gtk-demo) 663605 Fix event-state of many event types on quartz November 10, 2011 Alexander Larsson ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list

Hiding a widget does not count as a visibility notify obscured event as it appears that the obscured attribute is intended to cover cases where one unhidden widget obscures another. On this approach, whether something is unobscured is not the same as whether something is visible. To find out whether a widget is visible in the sense in which you intend it, you probably need to call GTK_WIDGET_VISIBLE(), which will reveal whether gtk_widget_hide() has been called on it.

The way its currently set up means its impossible to get module loadind gdk-thread-safe in all cases. Its not really possible to drop the lock in the other case, so the only solution is to take the lock in this case.

Quite often I've had a situation where I've needed to collect several pieces of information from various asynchronous sources, and then act on them as a group only once some portion of that information is available. This is becoming increasingly important as we start working with more and more remote DBus services, web services, Corba/Orb/whatever-its-presently-called services, and the list goes on. Data life cycle and flow management keeps being a problem. You need to: - use a signal to catch data when it becomes available - store that data somewhere - distribute that data to other places when it becomes available - clean up the data when it's no longer needed - safely handle data sources failing or disappearing - manage re-try timeouts, age invalidation timeouts, etc. I sort of feel that what's needed, is a GWish which is a higher-level GBoxed embodying the whole data life cycle management, and I'm wondering whether there are any plans or similar ideas in the works, or even just whether anyone else has a working example of tackling a similar situation. My starter concept is this; GWish will - hold a piece of data, when it's available - can be asked to obtain its data if it doesn't have it - can be dependant on other GWish's (dependant data) - ask any depedant GWishes for theirs when it is asked - invoke a callback when ALL dependant data is available - can be given the data to hold at any time (usually by the callback) - signal when its data is ready (ie. when its data is set) - only ask dependant GWish's when it itself is asked - provide a helper function to perform the ask, and then wait - allow the data to be invalidated without destroying the GWish - be used internally (or at least faked externally) by async properties - propagate data invalidation (unless blocked by a flag or ignored) - allow some dependant data to be flagged as optional - allow the data set callback to fail after requesting more data - optionally count a dependency as a reference on that GWish - use weak references to clean up non-referencing dependencies - support relevant timeouts with automatic timeout cleanup - optionally destroy itself if a dependancy gets destroyed An application can then tie together various pieces of required data from any source (either GWish-compatible or wrapped in an external GWish), even user interaction, by having the final GWish dependant on other GWishes, some representing other intermediate shared data, and others representing source data, or simply stages of processing to ensure certain events occur in order regardless of what order their data becomes available. This sounds quite nice actually. There are many cases where something like this would have helped me. Another possible name for this is GFuture, as such objects are about information or other things that'll be availible in the future. One major problem about doing things like this in C is that you constantly have to define and allocate small structs to keep the data you need for the completo operation. If we could somehow make this easier that would be a large win. I don't know a great approach to do that offhand though. Some form of user data is one possibility, but I'd really like it to betype safe and without using strings as API. I guess a GFuture/GWish needs to be some form of container that you can grow in size by adding a struct of your own data to it. Maybe we can do it via a macro g_future_push_struct (future, struct LocalOpData, free_op_data) which grows the size of the object and puts the struct at the end. You'll pop it at end to free it. Of course, such serial/stack-like data management might not be general enought to handle things like parallel async operations. Maybe just a way to add the struct (undefined where) to the GFuture and then you'll get a pointer to the struct inside the GFuture in the completion callback... ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list

Hi, first of all sorry about my English mistakes.
I've made a shared object (DLL) which is loaded by Mozilla Browser.
When I try to call a gtk_message_dialog_new() from this dll class instance

I have a suspicion that there is a conflict with Mozilla GTK instance even
after a successful gtk_init_check() calling, indeed this same code has
been successfully executed by a stand alone application (don't use GTK
functions).
Bellow is the snippet from the dll:
...

int argc = 0;
char** argv = 0;
if (gtk_init_check(argc, argv))
GtkWidget* dialog = gtk_message_dialog_new (NULL,

GTK_MESSAGE_ERROR,
GTK_BUTTONS_CLOSE,
Dummy message for test);
gtk_dialog_run (GTK_DIALOG (dialog));
gtk_widget_destroy (dialog);
gtk_main();
}
}
And this the error:

question regarding pixbuf
hello, i have a problem when i load images with a certain size. Normally the rowstride given with gdk_pixbuf_get_rowstride is calculated with width of the image multiplied with the number of channels in the image. But if i load an RGB Image with for example 314px*240px in size I get an rowstride of 944 instead of 942. If i load an image with 324px*248px I get an rowstride of 972 which is correct (324 * 3). It doesn't matter if the image is PNG or JPEG. Is this a bug or am I doing something wrong? Here is code i use to load the image and read the informations. image_filename = gtk_file_chooser_get_filename(GTK_FILE_CHOOSER(file_chooser)); original = gdk_pixbuf_new_from_file(image_filename, NULL); width = gdk_pixbuf_get_width(original); height = gdk_pixbuf_get_height(original); rowstride = gdk_pixbuf_get_rowstride(original); n_channels = gdk_pixbuf_get_n_channels(original); Thanks in advance Alexander ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
Re: What is the proper way of markig translations of static array initializers
The context is stripped when the string is *used*, for marking it is irrelevant whether it has context or not, so mark it normally with N_(). I am sorry but this does not work. When I mark strings simply with N_() the context information is not stripped away - in fact the original string in English gets shown *with* the context info - no translation gets shown even though the string is translated. When I mark the strings with Q_() or N_(Q_()) or Q_(N_()) I get such mistakes: gnomine.c:88: error: initializer element is not constant gnomine.c:88: error: (near initialization for ‘scorecats[0].name’) gnomine.c:90: error: initializer element is not constant gnomine.c:90: error: (near initialization for ‘scorecats[2].name’) gnomine.c:91: error: initializer element is not constant gnomine.c:91: error: (near initialization for ‘scorecats[3].name’) Any other ideas?

What is the proper way of markig translations of static array initializers
Hi guys, The docs: http://developer.gnome.org/doc/API/2.0/glib/glib-I18N.html state that N_() Marks a string for translation, gets replaced with the untranslated string at runtime. This is useful in situations where the translated strings can't be directly used, e.g. in string array initializers. How to add the addorning prefix in similar cases? (Like using Q_()).

Color selection
Hi All, I have a problem with a color selection dialog. The RGB values in the dialog itself are shown as 0..255 for each of the red, green, blue; but the values, returned by gtk_color_selection_get_current_color (colorsel, color) in color.red, color.green, color.blue are in the range 0..65535. How can I convert them to the 0..255 for to be able to get Windows compatible long value by color.red + color.green*255 + color.blue*65535 ? -- Regards, Alexander http://kresin.belgorod.su ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list

Customizing multiple selection behavior in TreeView
There is a TreeView widget whose TreeSelection's mode is SELECTION_MULTIPLE. I'd like to change how a single mouse click (and any of the equivalent actions from the keyboard and other input methods) on a row impacts the selection. The rest of the selection UI should behave as usual: Ctrl+click toggles one row, Shift+click selects a range, Ctrl+A selects all, etc. By default when the user clicks on a row, the selection is reset so that only the row clicked becomes selected. Instead of that, I'd like to make it toggle the selection of the row while leaving other rows alone (that's what Ctrl+click does). I've read the relevant parts of the API docs but still can't come up with a clean way to do that. Could you please describe such a way or give any clue about the relevant documentation I might have missed? By `clean' way I mean reusing what is already in GTK+ rather than reimplementing it. Such code duplication can result in UI inconsistencies over platforms and input methods, especially as time goes by. I'm a GTK+ newbie using the Python wrapper.

howto mix gtk and network
Hi, i plan to program a little game which also should playable over network and i need a some ideas for the beginning. I know the network basics. For example at the start of the game one player act as a server chooses the map and the number of max. players and other players can join. (Like in CC Generals or HW2) So what i need is a function which polls regularly every 0.5 second or so at the given port.

Problem or Bug??
Hi all i have a normal combobox created with gtk_combo_box_new_text and filled it with text with gtk_combo_box_append_text works fine. Now i have the bug like http://bugzilla.gnome.org/show_bug.cgi?id=302696 so i try to find another solution. Now i have an gchar* array with the text to be insert into the combo_box. So i use gtk_combo_box_get_active to retrieve the current selected and return array [selected] but it returns always -1 which means nothing is selected even with gtk_combo_box_set_active (combo_box,3).

i created some radiomenuitem with this.

tmp = Gruppe +outStream.str();
Widgets_MainWindow.menugroupitems[i] =

g_signal_connect ((gpointer) Widgets_MainWindow.menugroupitems [i],
activate, G_CALLBACK (on_menugroup_items_activate), (gpointer) i);
}
(don't laugh about the stream thing. If someone could give me a hint to
make that better would be great.)
and this is the callback:
void on_menugroup_items_activate (GtkObject *object, gpointer user_data)
{
cout Gruppe (int) user_data endl;
}
So the callback just print the number of the chosen group.
And this work.
But
1. During compilation i get a warning about
'cast to pointer from integer of different size'
for the g_signal_connect line. How can i avoid this?
2. It is normal that the callback is called twice?
For example if group 3 is marked and i change to 5 i get
Gruppe 3
Gruppe 5
then marking group 9
Gruppe 5
Gruppe 9
Is that normal?
3. When i choose group 1 the callback always produces
Gruppe 1
Gruppe 0
regardless from the previous group.
Why?
any ideas would be much appreciated..

drawing area and event order
Hi everybody, i have a drawing area in my application and conncted following signals realize, unrealize, configure_event and expose_event. And it works... The code: Widgets_MainWindow.drawingarea1 = gtk_drawing_area_new (); GTK_WIDGET_SET_FLAGS (GTK_WIDGET (Widgets_MainWindow.drawingarea1), GTK_CAN_FOCUS); gtk_widget_show (Widgets_MainWindow.drawingarea1); gtk_widget_add_events (Widgets_MainWindow.drawingarea1, GDK_BUTTON_PRESS_MASK | GDK_BUTTON_RELEASE_MASK | GDK_BUTTON_MOTION_MASK); gtk_table_attach (GTK_TABLE(Widgets_MainWindow.table1),Widgets_MainWindow.drawingarea1, 1, 2, 1, 2,(GtkAttachOptions)(GTK_EXPAND | GTK_FILL), (GtkAttachOptions) (GTK_EXPAND | GTK_FILL), 5,5); The events are properly connected, that works for sure. I thought the realize event is the first event raised, but it isn't. The first one is configure_event. And it doesn't matter in which order the code is. I want to ini a class in the realize event. I just tried gtk_widget_realize (Widgets_MainWindow.drawingarea1); before the gtk_widget_show (Widgets_MainWindow.drawingarea1); but then no realize event occurs. Why is that??
