[Development] quickcontrols has now a hard dependancy on widgets.

[gunnar at sletta.org]

Configure qtbase with "-no-widgets" and all widget dependencies should be gone from both Qt Quick and from Controls.

HI Gabriel,
I didn't know that, but i don't want any widgets dependency for a qml application, neither on desktop nor anywhere else.

Gunnar

Hi Gunnar,

You can always rebuild QtQuick Controls making sure you add CONFIG += no_desktop in the .pro file. The widgets dependency is automatic if widgets are present except on mobile platforms (which, paradoxically, exclude embedded).

Hi,
Recently i deteced that quickcontrols plugim has started to add a hard dependency on widgets ( on wec2013 and win32 at least ).
dpends.exe is showing

as imported functions from Widgets library.

In contrast to this the quickcontrols dialog plugin has only a soft dependency via qpa, because of the possibility to use the widgets dialogs as a fallback.
Ir is very surprising to have a dependency on widgets, which loads this huge dll on our wec2013 platform into memory ( for performance reasons paging of exe/dll is switched off) . I admit that this does only happen if you also build widgets library, but i usually build as much a i can on a platform, even if i don't use it yet.

With this patch i now disable that dependency.

I would really appreciate a configure option for this.
