* we did (i.e. WM_SYNC_PENDING and WM_MOVE_PENDING are both set).
|
|||
|
* This is because window managers treat coords differently than Tk,

|||
|
* and no two window managers are alike. If the window manager moved
|
|||
|
* the window because we told it to, remember the coordinates we told
|

|
* it, not the ones it actually moved it to. This allows us to move
|
|||
|
* the window back to the same coordinates later and get the same
|
|||
|
* result. Without this check, windows can "walk" across the screen
|
|||
|
* under some conditions.
|
|||
|
*
|
|||
|
* 2. Don't update wmPtr->x and wmPtr->y unless winPtr->changes.x
|
|||
|
* or winPtr->changes.y has changed (otherwise a size change can
|
|||
|
* spoof us into thinking that the position changed too and defeat
|
|||
|
* the intent of (1) above.
|
|||
|
*
|
|||
|
* 3. Ignore size changes coming from the window system if we're
|
|||
|
* about to change the size ourselves but haven't seen the event for
|
|||
|
* it yet: our size change is supposed to take priority.

|

|
* 1. It's important to distinguish ConfigureNotify events that are
|
|||
|
* coming in response to a request we've made from those generated
|
|||
|
* spontaneously by the user. The reason for this is that if the
|
|||
|
* user resizes the window we take that as an order to ignore
|
|||
|
* geometry requests coming from inside the window hierarchy. If
|
|||
|
* we accidentally interpret a response to our request as a
|
|||
|
* user-initiated action, the window will stop responding to
|
|||
|
* new geometry requests. To make this distinction, (a) this
|
|||
|
* procedure sets a flag for TopLevelEventProc to indicate that
|
|||
|
* we're waiting to sync with the wm, and (b) all changes to
|
|||
|
* the size of a top-level window are followed by calls to this
|
|||
|
* procedure.
|
|||
|
* 2. Races and confusion can come about if there are multiple
|
|||
|
* operations outstanding at a time (e.g. two different resizes
|
|||
|
* of the top-level window: it's hard to tell which of the
|
|||
|
* ConfigureNotify events coming back is for which request).
|
|||
|
* While waiting, all events covered by StructureNotifyMask are
|
|||
|
* processed and all others are deferred.
