How does the DrawingArea control work, such as drawing a line? Or insert pictures? Is there an example for reference?
Below is my code, but the program does not show the DrawingArea control when it runs. I give you the area that does not display the desired content!
uifcDrawingArea_ptr drawArea = uifcDrawingAreaFind(strDlg, strDrawArea);
drawArea->SetDrawingMode(uifcDRAWING_MODE_XOR);drawArea->SetDrawingColor(uifcColor::Create(0, 33, 255));uifcPoint_ptr screnPos = drawArea->GetScreenOrigin();xint areaWd = drawArea->GetWidth();xint areaHT = drawArea->GetHeight();uifcPoint_ptr pos1 = uifcPoint::Create(screnPos->GetX(), screnPos->GetY());uifcPoint_ptr pos2 = uifcPoint::Create(10, 10);drawArea->SetLineStyle(uifcLINE_STYLE_DOTTED);drawArea->SetLineWidth(10);drawArea->DrawLine(pos1,pos2);drawArea->DrawText("AAAAAAAAAAA",pos1);QQ:2571194117
