/* ccr . 2015 Aug 01 . Resize Main page and Main window.
|
|
*
|
|
* On very small legacy CRTs of about 15" (38 cm) RetroShare pages are
|
|
* initially too deep (too tall) to fit the screen at 1024x768
|
|
* resolution. Some can be shrunk down manually from their initial
|
|
* size. Others cannot. This patch tries to allow each page to be
|
|
* shrunk somewhat. Then code that runs elsewhere to fit the logical
|
|
* Main window into the physical screen will have a better chance of
|
|
* success. Notably, on Linux -- Gnome3 -- X11 systems, only when the
|
|
* Main window first fits entirely into the physical screen, can it
|
|
* then be maximized.
|
|
*
|
|
* This code is borrowed from a Stack Overflow post:
|
|
*
|
|
* o Darkgaze. "Resize QStackedWidget to the Page Which Is Opened." 23
|
|
* Jan. 2013. Online posting. Stack Overflow. 1 Aug. 2015
