Update Viewport after enabling an VisibilityOverrule

Hi Folks,

I have implemented an VisibilityOverrule which temporarily hides all entities of a drawing.

After it is enabled I us a jig class to interact with the user inside the cleared drawing. For all visual styles except wireframe2d, the entities are not hidden automatically. I have to refesh the viewport. The only way I found so far is to call the undocumented function acedColorSettingsChanged. After it is called. All entities are gone. I tried different ways to achieve the same result but without success.

I tried:

acedCommandS(RTSTR, L"REGEN", RTNONE)

acedCommandS(RTSTR, L"REGENALL", RTNONE)

acedUpdateDisplay

acedUpdate

AcGsView::invalidate()

AcGsView::update()

What else could it be? Any ideas?

Thanks,

Martin

Try:

acedCommandS(RTSTR, L"REGEN3", RTNONE);

It works so far. Sadly it does not regenerate the hidden entities for wireframe2d after the overrule gets disabled. They are still hidden afterwards. For wireframe2d I have to use REGEN instead.

Which is the fastest/simplest way to detect if wireframe2d is active?

AcDbObjectPointer<AcDbVisualStyle> pVstyle(acdbGetViewportVisualStyle(), AcDb::kForRead);
if (pVstyle.openStatus() == Acad::eOk)
{
    acutPrintf(L"\nVisual Style is %s WireFrame 2D", 
      (pVstyle->type() != AcGiVisualStyle::k2DWireframe) ? L"NOT" : L"");
}
