How can I render Text with transparent background over other widgets in GTK?

由 匆匆过客 提交于 2019-12-09 21:42:51
问题 I wish to render text with transparent/translucent background (or no background) over other gtk widgets like GtkImage or GtkButton etc. Primary goal is to have text display over Gtk Widgets (esp. GtkImage) in the background. I can render text on GtkFrame using pangocairo library but I am not able to get rid of the background of GtkFrame. I have seen examples of making GtkWindow transparent or translucent but I wish to have opaque GtkWindow with GtkLayout for placing the GtkWidgets, then place

pango attributes with pygobject

由 亡梦爱人 提交于 2019-12-04 11:55:39
问题 I have the following code, that uses pygtk: attr = pango.AttrList() attr.change(pango.AttrSize(( 50 * window_height / 100) * 1000, 0, -1)) attr.change(pango.AttrFamily("Sans", 0, -1)) attr.change(pango.AttrWeight(pango.WEIGHT_BOLD, 0, -1)) attr.change(pango.AttrForeground(65535, 65535, 65535, 0, -1)) self.label.set_attributes(attr) I'm trying to port it to pygobject, but there is no class Pango.AttrFamily, neither Pango.AttrWeight, neither Pango.AttrForeground (and I can not instantiate a

Open type font issue

问题 Basically,this is a problem of displaying a minority language. Let me make it brief: I've been trying to make my Opentype font(which has some features in it) work properly on non-windows(on windows, it works fine) platforms(Android ,iOS etc.). What I'm truly dealing with is a problem as complicated as displaying Arabic language(including glyph substitution,shaping etc.). I simply want to display the characters properly in my own software,because system wide support may be even more

Pango + Cairo; is there an existing approach for handling <img> style tags in text?

由 坚强是说给别人听的谎言 提交于 2019-12-01 05:11:38
Pango syntax supports some text only markup. As far as i can see this does not extend to embedding images as well. Looking around I cannot find much in the way of an existing implementation, but i havent done pango+cairo work before so i might be missing the obvious community for it. As far as i can tell a reasonable approach would be to just analyse a string, pull out any tags, create cairo images, and then modify the pango layout around them accordingly. It also seems like something someone might have done before. Im specifically looking for an answer on these questions: Does pango+cairo

Pango-WARNING **: failed to choose a font, expect ugly output

由 我的未来我决定 提交于 2019-11-30 21:47:12
问题 I'm getting this error when starting anything that uses the Pango library. I'm using Kubuntu 9.10. I've done 'sudo apt-get --reinstall install' on libgtk* libcairo* libpango* and fontconfig, with no luck. Could someone point me in the right direction? Thanks. 回答1: I did a lot of searching on this and never found a decent answer. My issue involved running virt-manager (an xwindows based utility) on a remote server. I have all the fonts on my xwindows box but not on the remote host. the i ran

Difference between GtkWindow and GdkWindow?

由 江枫思渺然 提交于 2019-11-27 21:19:39
问题 At the beginning of my Gtk-Gdk-Cairo-Pango app, I create the window: GtkWidget *window = gtk_window_new(GTK_WINDOW_TOPLEVEL); First, there is GtkWindow , but gtk_create_window returns GtkWidget , not GtkWindow , why? Then, some functions, like gdk_window_process_updates(..) require GdkWindow* . gtk_window_set_geometry_hints() on the other hand requires GtkWindow* . In documentation there is also GdkWindow* gdk_window_new() that returns GdkWindow . Sure there is documentation saying: A
