Add an interface method to show the options dialog at a specific
page. This is required since plugins can now embed their options
in the main options dialog, so they may also need a way to
force this dialog to open.
Implement this in processing so that enabling additional providers
works again.
Since composer windows are now only created on demand, and
destroyed when the window is closed, the old interface methods
no longer apply. The new interface methods openComposers(),
openComposer(), closeComposer(), composerOpened(),
composerWillBeClosed() and composerClosed() are similar, but
only apply to composer windows when they are exist (i.e.
are currently open).
To access all compositions from a project, the project's
layoutManager() should be used instead.
Additionally, the new interface methods work with
QgsComposerInterface objects instead of QgsComposerView
objects. This should allow future hooks for plugins to interact
with open composer windows in a more useful way.
Allows new "map views" to be created in the main QGIS interface.
These are map canvases, but with limited functionality (ie
no use of map tools beyond pan tool).
Allows plugins to embed their options into the standard options
dialog, instead of implementing their own config dialog and having
to have extra menu items just for those...
Qt5 allows runtime detection of touch devices. This commit reworks
the current touch map tool by pulling its behavior into the normal
pan tool when a touch device is detected.
It avoids the need for a seperate map tool for touch interaction,
and also avoids having this tool always appear on the Windows
builds (regardless of the presence of a touch device)
Allows you to quickly hide all deselected layers. This is very handy
when you have a large project and want to quickly hide all except
for a couple of layers
* This is actually a followup to 87121d, which fixes leaks
& clarifies some docs. But I figured the ability to add
custom pages to the properties is worth highlighting as a
feature on it's own, or it may go unnoticed in the other
globe related changes!
