Detailed Description

This interface provides the means to transform between internal coordinates in 100th of mm and screen coordinates without giving direct access to the underlying view. Each view forwarder represents a specific real or virtual window. A call to <method>GetVisibleArea</method> returns the visible rectangle that corresponds to this window.

This interface is similar to the SvxViewForwarder but differs in two important points: Firstly the <member>GetVisArea</member> method returns a rectangle in internal coordinates and secondly the transformation methods do not require explicit mapmodes. These have to be provided implicitly by the classes that implement this interface. A third, less important, difference are the additional transformation methods for sizes. The reasons for their existence are convenience and improved performance.

Attention: \n

Note, that modifications of the underlying view that lead to different transformations between internal and screen coordinates or change the validity of the forwarder have to be signaled separately.

Member Function Documentation

GetVisibleArea()

virtual tools::Rectangle accessibility::IAccessibleViewForwarder::GetVisibleArea ( ) const

pure virtual

Returns the area of the underlying document that is visible in the corresponding window.

Returns

The rectangle of the visible part of the document. The values are, contrary to the base class, in internal coordinates of 100th of mm.

Implemented in SvxGraphCtrlAccessibleContext.

LogicToPixel() [1/2]

virtual Point accessibility::IAccessibleViewForwarder::LogicToPixel ( const Point &  rPoint ) const

pure virtual

Transform the specified point from internal coordinates in 100th of mm to an absolute screen position.

Parameters

rPoint

Point in internal coordinates (100th of mm).

Returns

The same point but in screen coordinates relative to the upper left corner of the (current) screen.

Implemented in SvxGraphCtrlAccessibleContext.

Referenced by accessibility::AccessibleShape::getBounds(), and accessibility::AccessibleCell::getBounds().

LogicToPixel() [2/2]

virtual Size accessibility::IAccessibleViewForwarder::LogicToPixel ( const Size &  rSize ) const

pure virtual

Transform the specified size from internal coordinates in 100th of mm to a screen oriented pixel size.

Parameters

rSize

Size in internal coordinates (100th of mm).

Returns

The same size but in screen coordinates.

Implemented in SvxGraphCtrlAccessibleContext.
