| I also had a similar problem. Here is how I ended up doing it... extern GttWidget * curdlg; // of current dialog void gettextwdht ( char * family , int ptsize , int weight , bool normalstyle , char * stringtomeasure , int * wdret , int * htret ) { PangoFontDescription * fd = pango_font_description_new ( ); pango_font_description_set_family (fd, family ); pango_font_description_set_style (fd, normalstyle ? PANGO_STYLE_NORMAL : PANGO_STYLE_ITALIC ); pango_font_description_set_variant (fd, PANGO_VARIANT_NORMAL); pango_font_description_set_weight (fd, (PangoWeight)weight ); pango_font_description_set_stretch (fd, PANGO_STRETCH_NORMAL); pango_font_description_set_size (fd, ptsize * PANGO_SCALE); PangoContext * context = gtk_widget_get_pango_context ( curdlg ) ; PangoLayout * layout = pango_layout_new ( context ); pango_layout_set_text ( layout, stringtomeasure, -1 ); pango_layout_set_font_description ( layout, fd ); pango_layout_get_pixel_size (layout, wdret , htret ); g_object_unref ( layout ); } You can 'borrow' any widget for this (I think). It worked with a dialog widget for me. I really wanted a PangoContext that is not associated with a widget, so the calculations can be carried out totally 'offline'. I could not see how to do that. If anyone knows, I would be interested in finding out. P.S. The code shown above combines getting a font and measuring it. The actual code I am using splits these into two steps for efficiency. ---- Hi, I'm banging my head trying to figure out how to measure the text width of a string to be displayed in a GtkCelRendererText. From the code I've found, I need a PangoContext and GtkCelRendererText has plenty of Pango properties but none that return a PangoContext. In addition, GtkCelRendererText is not a GtkWidget, so I can't use gtk_widget_get_pango_context(). I'm at a loss as to how to do this. Any ideas? |
