device->onsize() - or clearscreen question
device->onsize() - or clearscreen question
hi,
in my application i have to show more than the drawing on the screen, and in 1.12.04 i solved the problem of the all-covering background by setting the clearscreen-property to false. but in 1.13 this doesn't seems to work anymore. the background is all black. i tried cdwglayoutpapercustomizationpe drawpaper as described in another thread but without success... so, i thought maybe using a rectangle, just in the size of the drawing and positioned whereever i want it, in the onsize() statement, could be a solution. because in that case i wouldn't mind if just this little area has a non-transparent background.
but, the onsize() works not quite as i expected.
the drawing rectangle is positioned and sized as requested but - within this rectangle the drawing is displaced with the same distance as the rectangle is from the screeen edge. i.e. if my rectangle is positioned at 0,0 eveything is great, but if it's moved to 100,200, then the rectangle is still fine but the drawing starts at 100,200 within the rectangle - 200,400 from the screen edge. and the rightmost and downmost part of the drawing is out of the reclangle and not shown.
how to...
... get the onsize to always draw the drawing to position 0,0 within the rectangle?
... or get clearscreen to work again?
... or - whatever that will solve my problem with many items on screen.
would appreciate sample code to or very detailed instructions... not too familiar with the software...
thanks in advance

onsize problem
hello renninha,
i have just started writing my first dwgdirect project and i am having exactly the same problem with onsize. i am writing a basic dwg viewer that can be used as a control in a dialog. i want to leave room at the top of the control for a toolbar, but when i pass a non-zero "top" value to onsize, it produces a black area at the top of the viewer.
did you ever find a solution to this problem?
