Hey folks. I searched the example code and knowledgebase for info on this
API, without success.
I'd like to display an hourglass on the form during a short (1 to
1.5-second) operation, and then undraw it. I am concerned about doing this
as quickly as possible, to eliminate any flicker that may result from
operations that take very little time.
The first thing I thought of was creating a bitmap family in C'Tor, and
using DmGetResource() and WinDrawBitmap(). This works fine, but I realized
quickly that I would need manually to store the bits 'behind' where the
bitmap will go before I WinDrawBitmap(), and then restore them. Having
never done this, I realized that it might be easier if I could just make a
new Form Bitmap, and then hide/show it using FrmShowObject() and
FrmHideObject().
But I can't seem to get it to work. POSEr crashes on me when I try
'FrmShowObject', complaining about reading from an unallocated chunk of
memory.
Can someone show me the trick? I'm not sure what the two different IDs are
in the FrmNewBitmap call, I suspect they the culprit.
In Constructor, I created a 1-bit Hourglass1Bitmap as a PICT resource, ID
1000, and then a HourglassBitmapFamily as a tbmf resource, ID 1000. The
tbmf references the PICT.
FormPtr pForm = FrmGetActiveForm();
FormBitmapType* pFrmBMP =
FrmNewBitmap( &pForm, resIdOne, resIdTwo, x, y );
FrmShowObject (pForm, resIdTwo);
I'm not sure if this is the wrong approach, and what I should be using for
resIdOne and resIdTwo.
Can someone clue me in please?
