gtk2

问题 I use PyGTK and I want to get colors of a widget (for example bg color), I run such a code: gdkColorToRgb = lambda gc: (gc.red//257, gc.green//257, gc.blue//257) widget = gtk.HBox() ## for example style = widget.get_style() for i in range(5): print i, gdkColorToRgb(style.bg[i]) But it does not give colors of my current gtk theme(style). It seems to be for default gtk theme (my current theme is dark, while this code gives light colors) I use ArchLinux and PyGTK 2.24.0 (GTK 2.24.5) 回答1: I just

问题 I made a treeview with a treestore as model. The window is shown as expected, but when I click in the "+" to expand the items, I get this message: GLib-CRITICAL **: Source ID 221 was not found when attempting to remove it Here is my code: #include <gtk/gtk.h> /* compile with: */ /* gcc main.c -o boxy `pkg-config --cflags --libs gtk+-2.0` */ typedef struct { GtkWidget *toplevel; GtkWidget *treeview; } Widgets; enum { ITEM_PARENT, ITEM_CHILD }; typedef struct { gint tipo; gint id; gchar *nombre

问题 Trying to change background/foreground color....Using Gtk+ and C. GdkColor color; gdk_color_parse( "#0080FF", &color ); gtk_widget_modify_fg( GTK_WIDGET(button), GTK_STATE_SELECTED, &color ); gtk_widget_modify_fg( GTK_WIDGET(button), GTK_STATE_NORMAL, &color ); I am using above functionality but it is not giving any results. I am looking for something asked in this question(But in C): GTK: create a colored regular button how to Change Style of Button using button Style? Can anybody provide

问题 I have a desktop application written in Ruby that is using GTK2. It's just a small test application to play with GTK2, but I'm having problems achieving what I want to do. Is there any way using GTK2 to get at the titlebar (apart from setting the title), specifically to either add a button to it (beside the min/max/etc, B in the below diagram) or to add an option to the menu that pops up when you click the icon on the titlebar (A in the below diagram)? I'm thinking there might not be because

问题 I am trying to install Rgtk2 (dependency for rattle). I am using R thru Anaconda. I am getting the following error. In file included from Rgtk.c:7:0: /usr/include/gtk-2.0/gdk/gdkx.h:32:10: fatal error: X11/Xlib.h: No such file or directory #include <X11/Xlib.h> ^~~~~~~~~~~~ I tried the following workarounds as found in StackOverflow and other blogs.

问题 I have very strange problem with gtk.Image(). Simple question; how to update image? On window creation I create image and pack it… On that time I load image from disk. Now I start downloading image from url, and when it's done I just want to replace existing image with new one. I rewrite content of same file on disk and then do: pixbuf = gtk.gdk.pixbuf_new_from_file(image_path) self._user_avatar.set_from_pixbuf(pixbuf) I have tried self._user_avatar.set_from_file(image_path) and self._user

问题 I have written a GUI in R with RGTK2 and Tcltk that does a lot of fairly heavy calculations and aggregations on big data sets. I would like to find a way to stop the user interface from accepting user inputs while it is processing a large data set, and ideally, change the interface color, popup a dialogue, or change the mouse pointer to an hourglass/spinner to indicate to users that the application is active. The implementation that I want would look something like: gSignalConnect

问题 In my application, sometimes I need to disable most of the buttons and event boxes while a process is taking place (except the "cancel" button of course). Each event box contains a label which can be clicked. To make the user understand that these labels are clickable, I have underlined the texts and have made the cursor change when hovered over those labels. The problem is that when I disable an event box (make it insensitive), you can see a rather ugly artifact: So, I searched and found

问题 As a requirement to install OCRopus, I have successfully installed matplotlib on Mac OS X 10.9.1 by pip : $ sudo pip install matplotlib But after installing OCRopus the test didn't work because of laking this module: matplotlib.backends._backend_gdk . Reading this document and this question convinced me that my problems might gone if I reinstall matplotlib through: $ sudo port install py27-matplotlib +gtk2 But on Mac OS X 10.9.1 it seems there is a bug which I receive this error: Error:

问题 I've tried to search, but nothing seems to work. For example: Separate threads I am currently writing simple communication app in Python2.7 with PyGTK. I have background process, which is listening socket in while loop like that. I want to display message, when I receive it form server. But when I start gtk.main(), it obviously starts to loop again, so my listening loop doesn't working. I need to display new window for each message or close old window and display new window with all unread
