Detailed Description

Singleton to allow to choose certain behaviours of the framework.

The setters should only be used before creating any DockWidget or MainWindow, preferably right after creating the QApplication.

Member Enumeration Documentation

◆ CustomizableWidget

enum KDDockWidgets::Config::CustomizableWidget

List of customizable widgets.

Enumerator
CustomizableWidget_None	None.
CustomizableWidget_TitleBar	The title bar.
CustomizableWidget_DockWidget	The dock widget.
CustomizableWidget_Frame	The container for a group of 1 or more dockwidgets which are tabbed together.
CustomizableWidget_TabBar	The tab bar, child of Frame, which contains 1 or more dock widgets.
CustomizableWidget_TabWidget	The tab widget which relates to the tab bar.
CustomizableWidget_FloatingWindow	A top-level window. The container for 1 or more Frame nested side by side.
CustomizableWidget_Separator	The draggable separator between dock widgets in a layout.

Definition at line 95 of file Config.h.

◆ Flag

enum KDDockWidgets::Config::Flag

Flag enum to tune certain behaviours, the defaults are Flag_Default.

Warning: Only the default is supported on all platforms. Not all options work with all window managers, Qt does its best to abstract the differences however that's only a best effort. This is true specially for any option that changes window flags.

Enumerator
Flag_None	No option set.
Flag_NativeTitleBar	Enables the Native OS title bar on OSes that support it (Windows 10, macOS), ignored otherwise.
Flag_AeroSnapWithClientDecos	Deprecated. This is now default and cannot be turned off. Moving a window on Windows 10 uses native moving, as that works well across screens with different HDPI settings. There's no reason to use manual client/Qt window moving.
Flag_AlwaysTitleBarWhenFloating	Floating windows will have a title bar even if Flag_HideTitleBarWhenTabsVisible is specified. Unneeded if Flag_HideTitleBarWhenTabsVisible isn't specified, as that's the default already.
Flag_HideTitleBarWhenTabsVisible	Hides the title bar if there's tabs visible. The empty space in the tab bar becomes draggable.
Flag_AlwaysShowTabs	Always show tabs, even if there's only one,.
Flag_AllowReorderTabs	Allows user to re-order tabs by dragging them.
Flag_TabsHaveCloseButton	Tabs will have a close button. Equivalent to QTabWidget::setTabsClosable(true).
Flag_DoubleClickMaximizes	Double clicking the titlebar will maximize a floating window instead of re-docking it.
Flag_TitleBarHasMaximizeButton	The title bar will have a maximize/restore button when floating. This is mutually-exclusive with the floating button (since many apps behave that way).
Flag_TitleBarIsFocusable	You can click the title bar and it will focus the last focused widget in the focus scope. If no previously focused widget then it focuses the user's dock widget guest, which should accept focus or use a focus proxy.
Flag_LazyResize	The dock widgets are resized in a lazy manner. The actual resize only happens when you release the mouse button.
Flag_DontUseUtilityFloatingWindows
Flag_TitleBarHasMinimizeButton	The title bar will have a minimize button when floating. This implies Flag_DontUseUtilityFloatingWindows too, otherwise they wouldn't appear in the task bar.
Flag_TitleBarNoFloatButton	The TitleBar won't show the float button.
Flag_AutoHideSupport	By default it also turns off the float button, but you can remove Flag_TitleBarNoFloatButton to have both. Supports minimizing dock widgets to the side-bar.
Flag_KeepAboveIfNotUtilityWindow	Only meaningful if Flag_DontUseUtilityFloatingWindows is set. If floating windows are normal windows, you might still want them to keep above and not minimize when you focus the main window.
Flag_CloseOnlyCurrentTab	The TitleBar's close button will only close the current tab, instead of all of them.
Flag_ShowButtonsOnTabBarIfTitleBarHidden	When using Flag_HideTitleBarWhenTabsVisible the close/float buttons disappear with the title bar. With Flag_ShowButtonsOnTabBarIfHidden they'll be shown in the tab bar.
Flag_AllowSwitchingTabsViaMenu	Allow switching tabs via a context menu when right clicking on the tab area.
Flag_Default	The defaults.

Definition at line 67 of file Config.h.

◆ InternalFlag

enum KDDockWidgets::Config::InternalFlag

Enumerator
InternalFlag_None	The default.
InternalFlag_NoAeroSnap	Only for development. Disables Aero-snap.
InternalFlag_DontUseParentForFloatingWindows	FloatingWindows won't have a parent top-level.
InternalFlag_DontUseQtToolWindowsForFloatingWindows	FloatingWindows will use Qt::Window instead of Qt::Tool.
InternalFlag_DontShowWhenUnfloatingHiddenWindow	DockWidget::setFloating(false) won't do anything if the window is hidden.
InternalFlag_UseTransparentFloatingWindow	For QtQuick only. Allows to have round-corners. It's flaky when used with native Windows drop-shadow.
InternalFlag_DisableTranslucency	KDDW tries to detect if your Window Manager doesn't support transparent windows, but the detection might fail
InternalFlag_TopLevelIndicatorRubberBand	with more exotic setups. This flag can be used to override. Makes the rubber band of classic drop indicators to be top-level windows. Helps with working around MFC bugs

Definition at line 314 of file Config.cpp.

◆ setDockWidgetFactoryFunc()

void KDDockWidgets::Config::setDockWidgetFactoryFunc ( DockWidgetFactoryFunc func )

Registers a DockWidgetFactoryFunc.

This is optional, the default is nullptr.

A DockWidgetFactoryFunc is a function that receives a dock widget name and returns a DockWidget instance.

While restoring, LayoutSaver requires all dock widgets to exist. If a DockWidget doesn't exist then a DockWidgetFactoryFunc function is required, so the layout saver can ask to create the DockWidget and then restore it.

Definition at line 334 of file Config.cpp.

◆ setFlags()

void KDDockWidgets::Config::setFlags ( Flags flags )

setter for the flags

Parameters

flags the flags to set Not all flags are guaranteed to be set, as the OS might not supported them Call flags() after the setter if you need to know what was really set

◆ setFrameworkWidgetFactory()

void KDDockWidgets::Config::setFrameworkWidgetFactory ( FrameworkWidgetFactory * wf )

Sets the WidgetFactory.

By default DefaultWidgetFactory is used, which gives you FrameWidget, TitleBarWidget, TabBarWidget, TabWidgetWidget etc. You can set your own factory, to supply your own variants of those classes, for the purposes of changing GUI appearance and such.

Also potentially useful to return QtQuick classes instead of the QtWidget based ones. Ownership is taken.

◆ setMDIPopupThreshold()

void KDDockWidgets::Config::setMDIPopupThreshold ( int threshold )

◆ setTabbingAllowedFunc()

void KDDockWidgets::Config::setTabbingAllowedFunc ( TabbingAllowedFunc func )

Allows the user to intercept a docking attempt to center (tabbed) and disallow it.

Whenever the user tries to tab two widgets together, the framework will call func. If it returns true, then tabbing is allowed, otherwise not.

Example:

#include <kddockwidgets/Config.h>
(...)
 
auto func = [] (const KDDockWidgets::DockWidgetBase::List &source,
                const KDDockWidgets::DockWidgetBase::List &target)
{
   // disallows dockFoo to be tabbed with dockBar.
   return !(source.contains(dockFoo) && target.contains(dockBar));
}

KDDockWidgets::Config::self()->setTabbingAllowedFunc(func);

Definition at line 173 of file Config.cpp.

◆ tabbingAllowedFunc()
