GTK widget styles.
How would I set the style GtkWidget::focus-line-pattern in a gtkrc file? The documentation says it's a gchararray, but I'm not sure what syntax is required for that. I've tried text and numbers, both quoted and unquoted and not had nice results (2-3 huge lines). What I am trying to do is change the dashed pattern from "- - - " to "--- --- --- ". BTW, I also noticed that if I set "GtkRange::stepper-spacing = 20", the scrolling is broken if you put the slider at either extreme: when you next drag it, it jumps along by a few pixels. Is this a known bug? Thanks, Roger -- Roger Leigh Printing on GNU/Linux? http://gimp-print.sourceforge.net/ GPG Public Key: 0x25BFB848.

Re: Setting widget style such as button color, text size.
Hi Heechul, Labels and buttons don't have their own windows, so they don't have a background colour. If you want to set the colour separately, put them inside a GtkEventBox. I'm not sure about the flat frame. I think .gtkrc files are not so hard to write. The easiest way is to look at some themes that do something similar to what you want, and modify them.

GtkComboBox ? in Gtk+-2.3
Hi all,
I test the new GtkComboBox widget for a project.
But i have a problem, the items on this GtkComboBox are hidden, and i
don't know why.
Here is my source code, it's a small code, can you check it and send me
the right way to use GtkComboBox.
Thanks,

reading this more carefully, this is a perfect candidate for using a
GtkAdjustment. Just create it with the relevant parameters:
initial value
lower bound
upper bound
small step size
page step size
then when you create the spinbutton attach it to this adjustment.
in your code, when you want to change the value, set the value of the
adjustment and the spin button will change. connect to the
adjustment's "value_changed" signal if you want to know when the
spinbutton or your code has changed the value.
be careful to avoid feedback loops. write things like:
gfloat adjuster_value = gtk_adjustment_get_value (GTK_ADJUSTMENT(adjuster));
if (adjuster_value != parameter_value) {
gtk_adjustment_set_value (GTK_ADJUSTMENT(adjuster),
parameter_value);
}
this assumes that you have the parameter stored elsewhere in the
program (i.e. it can't actually be a GtkAdjustment itself).

Re: emitting a signal for refeshing entries
Hi,
Thank you all for the replies, but what I am looking for is a way to
send an "EXPOSE" signal to the main window and wiil this signal
propagate to all the widgets in this main window ?
I have the callback for "expose events" ready and I have used the
GtkAdjustment.
As it looks now I will have to send an "expose_event" signal to each
widget individually as this signal cannot be emitted/sent to all the
widgets at once ? There si no way to send a signal to all widgets at once ?

URGENT: Problem with GtkPaned
hello, i have a problem with GtkPaned.
The attached file is a source that reproduce the
problem (build with gtk+-2.2.3 under win32).
The problem is that when the user move the first paned
the widget in the second paned is
not redraw correctly. What can i do ? Is a bug or i am
wrong ?
This is a small problem but the release of application
is near.
NB: In the real application the problem appear also
when i use gtk_paned_set_position(): the widget
in the paned is not visible, but if i move with the
mouse the paned the widget magically appears.
thanks, hammer.

dynmically growing GtkTreeView from MySQL DB?
I'm writing an app that uses MySQL (currently but could use Unix ODBC later) as a backend. On one of the Data Entry screens, I want to show a treeview of the list of people added or are in the DB. I need the list to display quickly and be updated as new people are added. The TreeView set up as a list as opposed to a tree. Additionally, I want the data entry person to be able to double-click on an entry and edit it in the data entry portion of the window, which means I need fast retrieval of that information. How really should I handle this? In particularly the dynamically growing nature of the view? Any and all help is greatly and urgently requested and appreciated. -- .''`. Carl B.

About Pango === Pango is a library for layout and rendering of text, with an emphasis on internationalization. Pango can be used anywhere that text layout is needed, though most usage so far as been in the context of the GTK+ widget toolkit. Pango forms the core of text and font handling for GTK+ 2. Pango is designed to be modular; the core Pango layout can be used with four different font backends: - Core X windowing system fonts - Client-side fonts on X using the Xft2 library - Direct rendering of scalable fonts using the FreeType library - Native fonts on Microsoft platforms Dynamically loaded modules then handle text layout for particular combinations of script and font backend. Pango-1.2 ships with a wide selection of modules, including modules for Hebrew, Arabic, Hangul, Thai, and a number of Indic scripts. Virtually all of the world's major scripts are supported. As well as the low level layout rendering routines, Pango includes PangoLayout, a high level driver for laying out entire blocks of text, and routines to assist in editing internationalized text. More information about Pango is available from http://www.pango.org/. Pango depends on version 2.2.0 or newer of the GLib library; more information about GLib can be found at http://www.gtk.org/. Overview of changes between 1.2.x and 1.3.0 === * Share modules between the FT2 and Xft backend. Export PangoFcFont and PangoFcFontMap base classes so that other fontconfig based backends can be written and use these same modules. * Redo module system to use GTypeModule and work much like GTK+ theme engines and input method modules. * Change modules to declare coverage by script, rather than by code point. Add a ->covers callback so that modules can dynamically decide whether they can cover a particular codepoint with a given font. (This will allow multiple modules to handle a script for different types fonts.) * Complete rewrite of itemization pass. Now uses script information to improve language tags. This solves problems with incorrect language tags resulting in drastically wrong fonts being selected by fontconfig. * Add backspace-deletes-character PangoLogAttr; will allow proper deletion behavior for non-Western scripts. [Noah Levitt] * Add pango_fc_font_kern_glyphs(), which speeds up kerning a lot over doing it pair-by-pair. [Soeren Sandmann]. Kern in the Xft backend as well as the FT2 backend. * Remove the X font backend, except a minimal set of stubs to maintain binary compatibility. * Many improvements to pangoft2topgm to allow displaying PangoMarkup, saving to different file formats, etc. * Convert build system to automake-1.7; many cleanups and improvements.

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. However, the licensing terms for GTK+, the GNU LGPL, allow it to be used by all pdevelopers, including those developing proprietary software, without any license fees or royalties.
