This class behaves like dynamic QSplitter and can hold up a number of various viewports that can be customly resized. Usually this container serves as a layout class for containers in the tab widget.

View port container should always include at least 1 view port. Otherwise there is no point of having the container at all! That's why the initial viewport is required in constructor already.

Constructor & Destructor Documentation

CAViewPortContainer::CAViewPortContainer

(

QWidget *

parent

)

Constructs the initial container having v as the initial viewport and a parent widget p.

References setCurrentViewPort().

Here is the call graph for this function:

CAViewPortContainer::~CAViewPortContainer

(

)

Removes all the viewports and finally destroys container.

Warning

This destructor also deletes the viewports!

void CAViewPortContainer::addViewPort	(	CAViewPort *	v,
		QSplitter *	s = 0
	)

Adds and registers the given viewport v to the splitter s or the top splitter if not specified.

Here is the caller graph for this function:

CAViewPort * CAViewPortContainer::splitHorizontally

(

CAViewPort *

v = 0

)

Splits the given viewport v horizontally or the last used viewport if none given. Horizontal split uses vertical splitter. Returns the newly created viewport.

(

v = 0

)

Splits the given viewport v vertically or the last used viewport if none given. Vertical split uses horizontal splitter. Returns the newly created viewport.

Here is the caller graph for this function:

CAViewPort * CAViewPortContainer::unsplit

(

CAViewPort *

v = 0

)

Unsplits the views so the given viewport v is removed. If no viewport is given, removes the last active one.

Returns

The pointer to the viewport which was removed. If none was removed (ie. the given viewport was not found or there are no viewports left) returns 0.
