Problems building pango-1.18.0 on Mac
Hi, I've recently got a Mac on which I try to install all the GTK+ stuff :-) I've come a long way, but now I seem to be stuck with the building of pango-1.18.0 I'm trying to build with X11 support and have all X11 installed on the Mac (as far as I can tell - I'm still very new to Mac...) In the directory where I have extracted the pango-1.18.0 I run ./configure --with-x --x-includes=/usr/X11/include --x-libraries=/usr/X11/lib The configure succeeded well. Now I run make Runs fine until the linking phase where it complains with: --- Undefined symbols: _pangoft2_viewer, referenced from: -viewers in pango-view.o _pangocairo_viewer, referenced from: -viewers in pango-view.o ld: symbol(s) not found --- It seems to me to be something internally in the pango-package that can't be found when linking? Can someone help me through this problem?

gtk_window_set_decorated(x, FALSE)

Unforgiving GtkEntry
Hi, I've discovered a problem that I can't really determine if it is a bug or intended. I have a entry in which I insert some text using gtk_entry_set_text(). Unfortunately it happened that it was not completely UTF-8 - one of the characters in the middle was not UTF-8. Okay, I get a warning - that is absolutely fair. No doubt, an invalid string was given to the GtkEntry. I tried afterwards in the GUI to delete the text and enter a new text and read the text using gtk_entry_get_text(). I printed the text and discovered that the invalid characters were present in the read text! This may be correct seen from the point of view that I was only able to delete the characters I could actually see displayed in the entry, but on the other hand, the gtk_entry_get_text() should return an UTF-8 string I would expect. I also tried to overwrite the invalid text with a new shorter, but correct UTF-8 text string using gtk_entry_set_text(). When I read the text using gtk_entry_get_text() I still got some invalid characters back from the previous erroneous text. I this in any way correct behaviour? So the situation is quite locked after entering an invalid string, is that intended?

Unfortunately no toggle_button is found during the child-scan.
Actually the scan found only one widget in the gtkcomboboxentry, which
to me seems quite strange as I would have expected at least two.
(Checke by setting another print-statement in the scan_children())
I haven't been able to determine which widget it actually detected, as I
hevent found any good way of getting the type extracted from the widget
in a human readable way.
Do you have any clue on what is going on here?

The test you ran was that on a 2.4.13 or 2.5.5 or both?
About GTK_IS_... macro:
There are six std macros defined by every Gtk+ class. They are used for:
2* type checks (GTK_IS_...[_CLASS])
2* obj casts (GTK_...[_CLASS]), e.g. GTK_BIN( my_combo )-child
1* the type system internal type (GTK_TYPE_...)
1* get the objs class (GTK_..._GET_CLASS)
Thanks for the explanation.
E.g. if you look into the code, you will find a lot of
g_return_if_fail( GTK_IS_...( combo ) );
For more information read the Gtk+ tutorial and
http://www.le-hacker.org/papers/gobject/
I think these six macros should also be in the reference manual.
I expect to be able to find any (public) available function/macro in the
reference manual.
And be sure you use gtk_container_forall not gtk_container_foreach!
I checked in the reference manual before use - and know the difference!

Changing background color of text in statusbar

I simply want the background of the text to be red, but it seems to be

to the right in the statusbar - not quite what I want!

gtk_widget_modify_bg(active_statusbar, GTK_STATE_ACTIVE, red);

Changing background color of text in statusbar
Hi,
I've been trying to change the background colour for the text dispalyed
in a statusbar, but I don't get it as I want it!
I simply want the background of the text to be red, but it seems to be
quite difficult - or I've just missed something. (Probably the later :-)
I've tried a lot of things including use of 'private' variables in the
GtkStatusbar structure!
The following sample code gives me a red frame and a little red square
to the right in the statusbar - not quite what I want!
Sample code:
gtk_widget_modify_bg(active_statusbar, GTK_STATE_NORMAL, red);
gtk_widget_modify_bg(active_statusbar, GTK_STATE_ACTIVE, red);
gtk_widget_modify_bg(active_statusbar, GTK_STATE_PRELIGHT, red);

Steffen Gutmann wrote: Hi Egon! Egon Andersen wrote: So, it seems their implementation isn't complete yet... Well, yours isn't complete either ;-) I think, they were talking about scrolling and that the solution in 59799 didn't cover it correctly. I checked the scrolling in my version and seems to be ok. There is nothing wrong with the scrolling in the solution in 59799. We just had some discussions about how the code could be written, but the results are the same. There was a little about clamp, where I had a short brain-damage, as at the time where Owen Taylor commented on it, it was almost 6 months since I looked at this. (And now it is another year.) Have you tried to set RTL and used your solution? You have default LEFT, which I believe will not be what was expected when RTL. 59799 respects the RTL and an adjustment equal to 0.0 is the default. An adjustment of 1.0 will do the opposite, which in LTR means right adjusted, but in RTL means left adjusted. What is missing in 59799 is commented by Owen Taylor, something like the g_return_if_fail and then the description of the functions should be improved. Yes, I agree. Actually, the whole gtkentry.c could benefit from some more comments... Couldn't agree more ... The solution in 59799 give the possibility to have any alignment, not just right, left and center as your proposal. This is something I want to discuss. In principle I see no problem in making GtkEntry having any alignment (in [0;1]) and the solution would be straight-forward (given what I have now). But is there any need in having an entry aligned other then left, center, or right? For, a label I see that one might want to have it aligned with a value of 0.1 (so mainly left but also using little space on the left if available), but for a GtkEntry? Would that make sense? Editing a GtkEntry with an alignment of 0.1 might be a strange thing. I only see left, center and right useful like in an text editor: most time you have text left aligned, for numbers you might choose right aligned, and for something pretty, you center it. Well, my experience it that whenever something is restricted, someone would like to do something that was not possible due to the restrictions. Furthermore there must be made test-instructions. How about, if the entry example covers this? A new choice-type field could be added to the example where the user can select the justification. I believe a test instruction is a little more than just an example. ___ gtk-list mailing list [EMAIL PROTECTED] http://mail.gnome.org/mailman/listinfo/gtk-list
g_spawn_command_line_async and MinGW
Hi,
I've used g_spawn_command_line_async with success on Linux RH7.3 and
have tried to make it work on MSWindows too.
I've noticed the special 'syntax' to be used when a command-line is used
on windows and tried a lot of different things, but I always end up with
an GError:
domain: 543 (g-exec-error-quark)
code: 19 (G_SPAWN_ERROR_FAILED -- I think?)
message: Failed to execute helper program
actual program line is:
result =
g_spawn_command_line_async('C:\\Programmer\\mozilla.org\\Mozilla\\mozilla.exe',
error);
I'm wondering if this is related to MinGW do not have fork()?
Any other idea about how to launch a heavy application from within my
application on MSWindows?
Maybe g_thread_create() and execl(), but that I can't make working on
Linux RH7.3 -- I get Real-time signal 1 after a while; the 'child'
starts and the 'parent' dies. This was not what I wanted ;-)

Hi, I've got a problem in an application, that some of my widgets in a notebook-page are not shown before I click on a button in the same notebook-page.

I've tried to use gdk_window_process_all_updates() and hoped that it could somehow force redraw of the window/notebook-page, but without any luck. These widgets are created during a phase where I have frozen the display using gtk_widget_freeze_child_notify() and later it is thawed by gtk_widget_thaw_child_notify(), so I would expect that widgets are drawn after the thaw??

You have somehow broken GTK+ updates in GTK+ are supposed to just work, so there is no function to call make updates work. If you can create a small standalone test, it would be worth filing a bug. It is a quite hairy combination of notebooks, tables and containers, so it will probably take a looong time to cut it down and still have the problem. Unfortunately this will not go to my highest priority list. These widgets are created during a phase where I have frozen the display using gtk_widget_freeze_child_notify() and later it is thawed by gtk_widget_thaw_child_notify(), so I would expect that widgets are drawn after the thaw?? I don't think those functions do what you think they do... unless you are implementing a container widget, there should be no reason to call them (though I wouldn't expect them to have much effect one way or the other.. notification of child properties is basically there for GUI builders.) Removing these calls would be the first step to take. Well, removing these calls didn't solve the problem at all. Actually, these freeze/thaw are making the update both faster and smoother. The intension is to prevent a lot of table-resizing during the population of the tables with widgets of different sizes. If there are better ways/more correct ways to do this, I'll be pleased to hear about this. So in my application freeze/thaw do have effect, but does not seem to have any relation to the problem in question.

I also have scrollable windows and want a specific entry to be visible - just another complication I imagine. Do anyone have hints or ideas? Traditionally the user just click on the notebook tab and gets the selected page and scroll until the specific entry is visible, but I want to be able to select the page from the application and make the entry visible. (The reason is that a post validation of entry data has shown that the entry data is invalid and the user has to correct it.)

I think you need gtk_notebook_set_page() I thought of this function, but then I need to make it top-down. I can in no way just say that I want to see the page (and its parents) containing a specific widget? I can probably use the gtk_widget_get_parent/gtk_widget_get_ancestor to find the parent notebook(s), so I try that even though it seems a little clumsy. BTW When I used gtk_widget_get_ancestor(notebook1, GTK_TYPE_NOTEBOOK), I got the pointer equal to 'notebook1', not the parent notebook as I had expected. Is this the intended behaviour of gtk_widget_get_ancestor() or is it a simple bug? (It is easy to work around in a consistent way, so it is no big deal.) I also have scrollable windows and want a specific entry to be visible - just another complication I imagine. It depends on what sort of thing you're displaying. Widgets like clist, for example, have methods which will scroll to make a specific row visible. If it's not a clever widget, then you just set the adjustment on the scrolled window to the position of the child. It is 'any widget', so it can not be expected to be a clever widget :-) But how do I get the position of the widget, so that I can set the adjustment? Basicly what I have access to is the widget pointer. So I have to determine the position of the widget relative to the scrolled window somehow...??

For example, if you know the widget that each notebook page is showing, you can do gint page = gtk_notebook_page_num( nb, my_page_widget ); gtk_notebook_set_page( nb, page ); (or have I misunderstood?) Basicly I just know the widget pointer, so it requires some processing to find the correct parent notebooks and setting the page... but that part is close to working. The code you show is just a small but important part of this :-) To get one out, do gtk_widget_get_ancestor( widget-parent, GTK_TYPE_WHATEVER ) Approximately how I did it.

What are you using inside the scrolled window to layout your widgets? You might be able to just read child-allocation.x/y, or you might need to poke about inside the layout widget. Mostly a mix of vboxes and hboxes added some frames and sometimes tables. So it seems to be quite a job and still I'm totally confused about how to get the adjustment of anything at all. E.g. how do I get the adjustment of an entry inside a vbox? Best regards Egon Andersen ___ gtk-list mailing list [EMAIL PROTECTED] http://mail.gnome.org/mailman/listinfo/gtk-list

Transparent background in window?
Hi, Is it possible to make the background in a window transparent? The reason that I ask is that I have made a splash screen with an image that is not rectangular (transparent background) and I would like the window to appear as having the same shape as the image. I've been looking at gtk_style family, but I haven't found the solution. Any hints?

problem with check_button in notebook tab
Hi, [gtk2+] I've inserted a check_button in some notebook tabs, which works fine in my linux environment, but when I ported the code to windows, the check_button could not be set/unset and the connected tooltips didn't appear either. I don't have problems with check_buttons or tooltips in other places than in the notebook tab. Do someone know why there is this strange difference between the linux and windows versions? And do anyone have an idea about how I can get the functionality in windows. Best regards Egon Andersen ___ gtk-list mailing list [EMAIL PROTECTED] http://mail.gnome.org/mailman/listinfo/gtk-list
How do I remove a widget from a table?
Hi, I would like to remove one or more widgets from a table. The widget has been attached earlier by gtk_table_attach(). When I try to destroy the widget I get a segmentation fault (which I to some degree can understand), but how do I remove the widget the 'right way' ?

Text always selected in entry
Hi, GTK2: It seems that the default text in an entry is always selected when entering the field. How do I prevent that from happening. I've tried gtk_editable_select_region with start and end set to 0, but this does not help. Do someone have an idea about how I get past this problem? /Egon ___ gtk-list mailing list [EMAIL PROTECTED] http://mail.gnome.org/mailman/listinfo/gtk-list
