CEGUI (Crazy Eddie's GUI) Forums

I want to create my own font class just like this:
class ColorFont:public CEGUI::FreeTypeFont
{
public:
ColorFont(const CEGUI::String& name, const CEGUI::String& fontname,
const CEGUI::String& resourceGroup = "");
void drawTextLine (const CEGUI::String& text, const CEGUI::Vector3& position,
const CEGUI::Rect& clip_rect, const CEGUI::ColourRect& colours, float x_scale = 1.0f, float y_scale = 1.0f);
}
and overwrite the drawTextLine function, so I can change the font colour by the text.

However, when i compile it, these are something wrong , and I don't know how to solve,please help!!! I want a multicolour text.

It looks like you're not linking against the CEGUIBase lib.

CE.

but i have linked to it. if i don't use this class, the cegui performs very well in my game.I don't know what happened

Yeah, I just looked at the code for CEGUI::FreeTypeFont - it turns out we're not exporting the symbols from the DLL (because further subclassing is not actually the intended usage of those classes).

As a slight aside, the latest trunk code for CEGUI has some support for coloured text (along with lots of other things) - it's not interface compatible with the old version though and the code is still being debugged and tuned.
