|
|
* Overview:
|
|
*
|
|
* UI for the app is done on the main thread. The app itself
|
|
* is not in the taskbar or in the tray. The only way to get to
|
|
* it is to Alt+Tab to it. When you minimize it, it vanishes again.
|
|
*
|
|
* FEATURE -- someday create an optional tray icon
|
|
*
|
|
* Details:
|
|
*
|
|
* The main window
|
|
* is just a dialog box. The window we create is just a
|
|
* subclassed static control.
|
|
*
|
|
* By stealing an existing control, we don't need to register
|
|
* our own bogus class.
|
|
*
|
|
* We hide from the taskbar by having a hidden owner.
|
|
*
|
|
* We show up in Alt+Tab because the hidden owner is
|
|
* not marked WS_EX_TOOLWINDOW.
|
|
*
|
|
* We vanish on minimization by hiding ourselves, parking
|
|
* the minimized window "in outer space" so it doesn't bother
|
|
* the user. Then re-show it so it can take part in Alt+Tab.
|
|
*
|
|
*****************************************************************************/
|

|
|
/*
|
|
* These are the co-ordinates of outer space. Note that we can't base
|
|
* this on GetSystemMetrics(SM_C[XY]SCREEN) because the user might be
|
|
* running multiple monitors, and we need to be sure we are outside all
|
|
* monitors. So we pick a really absurd value for outer space.
