Summary
Please send values for parameter to SetDisplayFrames of VectorDraw Wrapper (vdraw.ocx).Aalso it appears if you set DisplayFrames to ShowAll you get a embeded CVdGrid control - how do I access that (send code example to fill it with either figure properties or general properties please).
Solution
The vdrawcontrol has exported the following methods for grid manage:
- SetGrid_SelectedObject , GetGrid_SelectedObject
- SetGrid_Font ,GetGrid_Font select a new TTF font for the grid example: SetGrid_Font("Tahoma");
- Grid_Refresh() // refresh the grid control
- Grid_Clear() // clears the selected object of grid
Also the DiplayFrame gets the following on or more following values :
- Default = 1 + 2 + 4 + 32,
- HideAll = 0,
- ShowAll = 1 + 2 + 4 + 8 + 16 + 32,
- ShowStatusBar = 1,
- ShowHorizontalScroll = 2,
- ShowVerticalScroll = 4,
- ShowPropertyGrid = 8,
- ShowCommandLine = 16,
- ShowLayoutTab = 32,
You can add the vdraw.ocx in a form and 3 buttons and write code like :
void CVdTest1Dlg::OnDocprop() // { // Select the document object in the property grid m_vd.SetGrid_SelectedObject(m_vd.GetActiveDocument()); } void CVdTest1Dlg::OnFigprops() { // Create a line and select the line in property grid m_vd.GetActiveDocument().New(); double p1[3] = {1,1,0}; double p2[3] = {2,2,0}; COleSafeArray vp1; COleSafeArray vp2; vp1.CreateOneDim(VT_R8,3,&p1); vp2.CreateOneDim(VT_R8,3,&p2); CvdLine line = m_vd.GetActiveDocument().GetEntities().AddLine(vp1,vp2); line.Invalidate(); m_vd.SetGrid_SelectedObject(line); } void CVdTest1Dlg::OnSelctionprops() { // Create a circle and a selection set with all objects in the entities collection and select the selection in the property grid m_vd.GetActiveDocument().New(); double p1[3] = {1,1,0}; COleSafeArray vp1; vp1.CreateOneDim(VT_R8,3,&p1); CvdCircle circle = m_vd.GetActiveDocument().GetEntities().AddCircle(vp1,1.0); circle.Invalidate(); CvdSelection set = m_vd.GetActiveDocument().GetSelections().Add("TEST"); set.Select(COleVariant("All"),COleVariant(),COleVariant()); m_vd.SetGrid_SelectedObject(set); }
