Hi Dxli
I try to draw QT style Text ( not RS_TEXT style) like below, but I did not
see the text displayed , do you know what's the reason ?
void QC_ApplicationWindow::testFont()
{
RS_PainterQt painter(getMDIWindow()->getGraphicView()->PixmapLayer2);
painter.setPen(0,0,255);
painter.drawText(0,0,"ABCD");
painter.end();
getGraphicView()->redraw();
}

Hi Johnson,
this is a known issue.
Currently, LibreCAD relies on stick fonts, and can not use the system fonts
either Bitmap or vector based.
A new mechanism of font support is needed
here for efficiency. Any help is welcome!
Thanks,
dxli
