Before we didn't need to update it because there was only 1
dock widget. But now, if there's more than one we need to set the
application's name instead of the dock widget's name as title.
Should allow MDI dock widgets to also accept drops.
Befor, each MDI "window" only had 1 dock widget, but now each
MDI "window" a layout of dock widgets.
This is implemented by nesting the actual dock widget inside
a wrapper drop area. This drop area gives the drop support.
There's still bugs and more tests to fix before merging.
We can't change the margins by subclassing MainWindow and overriding
centerWidgetMargins, since the margins are initialized in MainWindow's
constructor. This adds public API to MainWindow to allow us to change
the margins later on.
This is a public wrapper to MDILayoutWidget. The latter is private
and has internals we don't want to expose. Instead create a public
class with a thin API.
You no longer need to create a MainWindowMDI to have MDI support.
You can now have a normal MainWindow (with normal docking) and
add some dock widget that as a MDIArea as widget.
At points when a Rect is to be used to position a floating widget,
test to see if it overlaps any of the system's screens.
If it does not, adjust the Rect to within the closest screen edges.
Qt doesn't provide any way to know which window is directly
bellow the cursor. Generally this is fine since floating windows
are always on top of the main window. However, if Qt::Tool is removed,
then they can be behind, and KDDW can't know which window to overlay
the drop indicators onto.
This patch uses XLib's XQueryTree to solve this.
This is still experimental, hence disabled by default.
For now it's disabled by default, since it's experimental.
You can turn it on by passing -DKDDockWidgets_XLib=ON
Fixes bug #256
When we resize the main window then we also resize the inner
dock widgets in the same proportion (based on saved percentages),
during a resize we should not recompute those percentages due to
rounding errors.
They were being recomputed by mistake, since only the root Item
was blocking them, but the function recurses into inner items
Fixes#186
QQuickItem::parentChanged(QQuickItem *parent) passes the *new*
parent, not *this*
Fixes#243 which is actually invalid, but uncovered this bug.
For #243 you can just use sender(), or connect to a lambda that
captures the dock widget.
When using MainWindowOption_HasCentralFrame we have a persistent
central frame which is never destroyed. When restoring a layout
we shouldn't create it, as it exists already.
This change allows you to switch tabs via the context menu. The context
menu only shows up if you click on the empty area beside the tabs.
Can be tested with `--allow-switch-tabs-via-menu` option in the example.
Fixes#232
