The new current has the given index, or -1 if there isn't a new one (for example, if there are no tab in the QTabBar) This signal is emitted when the tab bar's current tab changes. void QTabBar:: currentChanged( int index) Member Function Documentation QTabBar:: QTabBar( QWidget * parent = nullptr)Ĭreates a new tab bar with the given parent. tabLayoutChange() notifies that the tabs have been re-laid out.įor subclasses, you might also need the tabRect() functions which returns the visual geometry of a single tab.tabRemoved() notifies that a tab was removed.tabInserted() notifies that a new tab was added.tabSizeHint() calcuates the size of a tab.The following virtual functions may need to be reimplemented in order to tailor the look and feel or store extra data with each tab: if a tab's label is "&Graphics", Alt+G becomes a shortcut key for switching to that tab. QTabBar creates automatic mnemonic keys in the manner of QAbstractButton e.g. The function currentIndex() returns the index of the current tab, count holds the number of tabs. There is also a slot, setCurrentIndex(), which can be used to select a tab programmatically. This is emitted whenever the current tab changes (even at startup, when the current tab changes from 'none'). The most important part of QTabBar's API is the currentChanged() signal. Many spreadsheets and other tab controls in which all the pages are essentially similar use TriangularSouth, whereas RoundedSouth is used mostly when the pages are different (e.g.
#CORNER TABBER WINDOWS#
Tab controls in windows other than dialogs almost always use either RoundedSouth or TriangularSouth. The choice of shape is a matter of taste, although tab dialogs (for preferences and similar) invariably use RoundedNorth. The shape property defines the tabs' appearance. Combining removeTab() and insertTab() allows you to move tabs to different positions. Tabs can be removed from the tab bar with removeTab(). The total number of tabs is given by count(). Tabs are added using addTab(), or inserted at particular positions using insertTab(). Set the text color for a particular tab with setTabTextColor(). The current text color for a tab can be found with the tabTextColor() function. Each tabs can be enabled or disabled individually with setTabEnabled().Įach tab can display text in a distinct color. The tabs's attributes can be changed with setTabText(), setTabIcon(), setTabToolTip(), setTabWhatsThis and setTabData().

Qt also provides a ready-made QTabWidget.Įach tab has a tabText(), an optional tabIcon(), an optional tabToolTip(), optional tabWhatsThis() and optional tabData(). It can be subclassed to tailor the look and feel. QTabBar is straightforward to use it draws the tabs using one of the predefined shapes, and emits a signal when a tab is selected.
