Hi,
I'm creating a magnifier plugin that implements the screen and window
plugin interfaces.
When the ccm_magnifier_screen_paint is called I create a new cairo context.
When the ccm_magnifier_screen_paint is called I try to read this cairo
context, but I'm getting a NULL value.
static void
ccm_magnifier_screen_paint(CCMScreenPlugin* plugin, CCMScreen* self)
{
CCMMagnifier* mag = CCM_MAGNIFIER(plugin);
static gboolean
ccm_magnifier_window_paint(CCMWindowPlugin* plugin, CCMWindow* window,
cairo_t* context, cairo_surface_t* surface)
{
CCMMagnifier* self = CCM_MAGNIFIER(plugin);
These lines just show how I cast the plugins to CCMMagnifier. I think
that the problem is in this place, but I don't know what is wrong. I
already look around for it, but doesn't find anything helpful.
Thanks,
Carlos.
