Comparison of GTK+, Tcl/Tk, Qt, wxWidgets

I am interested in information comparing using GTK+, Tcl/Tk, Qt, wxWidgets for writing GUI apps. A potential rewrite of a Tcl/Tk app. is under consideration. This app is to be supported on Unix/Linux and Window XP platforms. This app presently peforms some 2d drawing with user interaction from

Re: OpenGL Zoom / Pan

Try taking a look at the shapes.c example that comes with the gtkglext package. There are different ways do to them and it sort of depends upon how you plan on setting up the scene/object to view how how you plan to view it. For example, if you are viewing an object and want to simulate a zoom

How to perform 2D drawing on top of 3D OpenGL scene

I'm writing a program using Gtk and GtkGLExt. I have a drawing area which is using OpenGL to display a scene. I receive mouse motion events to rotate, translate, zoom, on this scene. In the display window, I would also like to draw some primitives on top of the scene rendered by OpenGL. For

Is there a way to use Pango Markup in GtkTextBuffer

Is there any convenient way to insert text using the Pango Markup language into a GtkTextBuffer. Such functions exist for GtkLabel and GtkCellView but I haven't seen any for GtkTextBuffer. If none exist, is there a reason they don't? Seems like such functions would aid in inserting text with

Signal for a button-2 paste event in a TextView

I have a GtkTextView with an associated GtkTextBuffer. I want to act on the condition when text is pasted into the textview or textbuffer when the middle mouse button is pressed. That is, suppose I have some text selected in another application (like a gnome-terminal, evolution, etc.) or when

Preventing cursor movement via mouse in GtkTextView

I'm attempting to create a command line input area for a GTK application using a GtkTextView with GtkTextBuffer. The user will type in commands and some output may be sent to the text buffer. After a command line is entered I make the text and any output not editable with a tag so they can not

Is it possible to put all necessary GTK runtime files in a single directory

I have a GTK application that I'm porting to run under Windows. This application is part of a package that has several other native Windows (non-GTK) executables all of which are to reside in a bin directory. The wish, desire, command of the project leader for this project would like

A few GtkFileChooserDialog questions

Couple of questions concerning the GtkFileChooserDialog. First, is it possible to make a GtkFileChooserDialog when in GTK_FILE_CHOOSER_ACTION_SAVE action to activate when the user presses Enter or Return in the name entry box so that one does not have to move the mouse to the Save button?

Re: Signal when the content of a GtkEntry is changed

I've had a similar/relate question that I've been curious about for some time. This emits a signal evertime the contents is changed. Unfortunately, taking action everytime it is changed may not be what is desired. What may be desired is when the changes are done. Suppose the entry contained a

Periodic and cross platform timers or alarms

I have a GTK program in which I would like to periodically have a function called (say every 1-5 sec) to perform a check on something and take a certain action depending upon the result. Usually the action will be to do nothing and return. I had first tried using a gtk_idle_add but this calls it

Re: Expose events not occurring from gdk_window_invalidate_rect

Yes it is idle a lot. Whenever your not moving the mouse or interacting with the GUI it should be sitting in main GTK event loop. On Fri, 2005-08-05 at 17:31 +0200, Sven Neumann wrote: Hi, Douglas Vechinski [EMAIL PROTECTED] writes: The problem I am having is that depending upon

Problems with GtkEntry's grabbing focus

Obtaining current value from a GtkHscale

I've been searching the GTK API trying to figure out what is probably a simple question. How do I get the current value from a GtkHscale scale bar? Since a GtkAdjustment is used to create the scalebar, I think that I could then use a gtk_adjustment_get_value(). However, I'm using glade-2 to

Mixing Windows API and GTK+

I have a gtk+ application that I developed under Linux. I ported to Windows using the MSYS/MINGW environments along with the native window compilation of GTK+. Now someone is interested in have me create a DLL out of this code so that it can be used as part of another Windows applications.

Getting libiconv_set_relocation_prefix error under Windows

I encountered the current problem I'm having about a year ago and thought I had figured what was wrong but can't seem to remember how to fix it. I am trying to compile the helloworld.c example in the GTK+ tutorial on Windows using the MSYS, MINGW environment and the Tor GTK+ Windows DLL's.
