| 63 | /* NOTES:
|
|---|
| 64 | * 1) The window ID for many DAX windows will default to zero. This is
|
|---|
| 65 | * because the window ID is taken from the hmenu parameter in the
|
|---|
| 66 | * CreateWindow call and this parameter will very often be 0 for child
|
|---|
| 67 | * windows. Since PM sends many control messages with only an id as a
|
|---|
| 68 | * means of identification, we are forced to substitute another window ID
|
|---|
| 69 | * internally when a window is created with an ID of 0. The private
|
|---|
| 70 | * bZeroId flag indicates when this happens. One disadvantage is that
|
|---|
| 71 | * the window ID as queried from PM for a DAX window will not be the real
|
|---|
| 72 | * DAX window ID when it should be zero. Because of this the windowId
|
|---|
| 73 | * member function should be used any time the ID is going to be passed
|
|---|
| 74 | * back to a DAX app (in a message or structure, for instance).
|
|---|
| 75 | * Fortunately this does not happen often.
|
|---|
| 76 | * 2) bEraseBkgnd is set to TRUE if the background needs to be erased. The
|
|---|
| 77 | * bPSEraseFlag tells BeginPaint what to set the PAINTSTRUCT fErased flag
|
|---|
| 78 | * to when bEraseBkgnd is FALSE. The bPSEraseFlag is necessary because
|
|---|
| 79 | * RedrawWindow must set bEraseBkgnd to FALSE if RDW_ERASENOW is used,
|
|---|
| 80 | * but BeginPaint must still set fErase to TRUE if the WM_ERASEBKGND
|
|---|
| 81 | * message returned FALSE.
