详细描述

Custom tabbar implementation for tab area that is shown on top of a dock panel widget.

The tabbar displays the tab widgets of the contained dock widgets. We cannot use QTabBar here because it does a lot of fancy animations that will crash the application if a tab is removed while the animation has not finished. And we need to remove a tab, if the user drags a a dock widget out of a group of tabbed widgets

成员函数说明

◆ areTabsOverflowing()

bool QxDock::DockTabBar::areTabsOverflowing ( ) const

This function returns true, if the tabs need more space than the size of the tab bar.

在文件 docktabbar.cpp 第 297 行定义.

◆ closeTab()

void QxDock::DockTabBar::closeTab ( int index )

This function will close the tab given in index param.

Closing a tab means, the tab will be hidden, it will not be removed

◆ insertTab()

void QxDock::DockTabBar::insertTab	(	int	index,
		DockTab *	tab
	)

Inserts the given dock tab at the given position.

Inserting a new tab at an index less than or equal to the current index will increment the current index, but keep the current tab.

在文件 docktabbar.cpp 第 110 行定义.

◆ isTabOpen()

bool QxDock::DockTabBar::isTabOpen ( int index ) const

This function returns true if the tab is open, that means if it is visible to the user.

If the function returns false, the tab is closed

◆ minimumSizeHint()

QSize QxDock::DockTabBar::minimumSizeHint ( ) const

overridevirtual

Overrides the minimumSizeHint() function of QScrollArea The minimumSizeHint() is bigger than the sizeHint () for the scroll area because even if the scrollbars are invisible, the required space is reserved in the minimumSizeHint().

This override simply returns sizeHint();
