=== Pango Text === | |||
{{Stub}} | |||
Successfully subclassed Pango::Renderer, and | |||
I'm also successfully showing an osg::Texture2D as element on the canvas, | |||
but when I try to copy an osgText::Glyph onto that texture, instead of a | |||
glyph I get a noise texture instead … the other issue I'm having is some | |||
ponter problem (a smart pointer of one CanvasPangoText instance only | |||
getting deleted upon the creation of the next instance, which leads to it | |||
wanting to delete something that was already deleted !?). | |||
On both problems I'm somewhat stuck, so it would be great if @James Turner | |||
<ja...@fl...> or @Hooray could take a look - the latest code is | |||
available at git.code.sf.net/u/thefgfseagle/simgear.git / branch | |||
canvas_pangotext, in | |||
simgear/canvas/elements/{CanvasPangoText,PangoRendererCanvas}.cxx<ref>https://sourceforge.net/p/flightgear/mailman/message/37795860/</ref> | |||
And the new element can be tested with the following Nasal code, after | |||
checking out the canvas_pangotext branch from | |||
git.code.sf.net/u/thefgfseagle/fgdata <ref>https://sourceforge.net/p/flightgear/mailman/message/37795864/</ref>: | |||
<pre> | |||
w = canvas.Window.new([200, 200], "dialog"); | |||
c = w.createCanvas(); | |||
g = c.createGroup(); | |||
t = g.createChild("pangotext"); | |||
t.setMarkup("<b>bold</b>"); | |||
w.show(); | |||
</pre> | |||
