A vertical or horizontal bar containing tabs that you can select.
You can use one of these to generate things like a dialog box that has tabbed pages you can flip between. Attach a ChangeListener to the button bar to be told when the user changes the page.
An easier method than doing this is to use a TabbedComponent, which contains its own TabbedButtonBar and which takes care of the layout and other housekeeping.
The placement of the tab-bar.

Returns true if the orientation is TabsAtLeft or TabsAtRight.
|
noexcept |
Returns the thickness of the bar, which may be its width or height, depending on the orientation.
References Component::getHeight(), and Component::getWidth().
void TabbedButtonBar::setMinimumTabScaleFactor | ( | double | newMinimumScale | ) |
Changes the minimum scale factor to which the tabs can be compressed when trying to fit a lot of tabs on-screen.
void TabbedButtonBar::clearTabs | ( | ) |
Deletes all the tabs from the bar.
void TabbedButtonBar::addTab | ( | const String & | tabName, |
Colour | tabBackgroundColour, | ||
int | insertIndex | ||
) |
Adds a tab to the bar.
Tabs are added in left-to-right reading order. If this is the first tab added, it'll also be automatically selected.
Changes the name of one of the tabs.
void TabbedButtonBar::removeTab | ( | int | tabIndex, |
bool | animate = false |
||
) |
Gets rid of one of the tabs.
Moves a tab to a new index in the list.
Pass -1 as the index to move it to the end of the list.
int TabbedButtonBar::getNumTabs | ( | ) | const |
Returns the number of tabs in the bar.
StringArray TabbedButtonBar::getTabNames | ( | ) | const |
Returns a list of all the tab names in the bar.
void TabbedButtonBar::setCurrentTabIndex | ( | int | newTabIndex, |
bool | sendChangeMessage = true |
||
) |
Changes the currently selected tab.
This will send a change message and cause a synchronous callback to the currentTabChanged() method. (But if the given tab is already selected, nothing will be done).
To deselect all the tabs, use an index of -1.
String TabbedButtonBar::getCurrentTabName | ( | ) | const |
Returns the name of the currently selected tab.
This could be an empty string if none are selected.
|
noexcept |
Returns the index of the currently selected tab.
This could return -1 if none are selected.
TabBarButton* TabbedButtonBar::getTabButton | ( | int | index | ) | const |
Returns the button for a specific tab.
The button that is returned may be deleted later by this component, so don't hang on to the pointer that is returned. A null pointer may be returned if the index is out of range.
int TabbedButtonBar::indexOfTabButton | ( | const TabBarButton * | button | ) | const |
Returns the index of a TabBarButton if it belongs to this bar.
Rectangle<int> TabbedButtonBar::getTargetBounds | ( | TabBarButton * | button | ) | const |
Returns the final bounds of this button if it is currently being animated.
