Detailed Description

A widget to wrap a single MultiWindowWidget, providing methods for switching the render window layout, remembering the last slice, magnification and cursor position.

IMPORTANT: This class acts as a wrapper for MultiWindowWidget. Do not expose MultiWindowWidget, or any member variables, or any dependency from MultiWindowWidget to the rest of the application.

Additionally, this widget contains its own mitk::RenderingManager which is passed to the MultiWindowWidget, which is itself a sub-class of QmitkStdMultiWidget. This means the MultiWindowWidget will update and render independently of the rest of the application, and care must be taken to manage this. The reason is that each of these viewers in a multi-viewer could have it's own geometry, and sometimes a very different geometry from other windows, and then when the "Bind Slices" button is clicked, they must all align to a specific (the currently selected window) geometry. So it became necessary to manage this independent from the rest of the MITK application.

Note: The requirements specification for MIDAS style zoom basically says.

magnification   : actual pixels per voxel.
on MIDAS widget :
2               : 3
1               : 2
0               : 1 (i.e. no magnification).
-1              : 0.5 (i.e. 1 pixel covers 2 voxels).
-2              : 0.33 (i.e. 1 pixel covers 3 voxels).
etc.

Member Function Documentation

bool niftk::SingleViewerWidget::AreDirectionAnnotationsVisible ( ) const

Tells if the direction annotations are visible.

bool niftk::SingleViewerWidget::AreDisplayInteractionsEnabled ( ) const

Gets the flag that controls whether the display interactions are enabled for the render windows.

bool niftk::SingleViewerWidget::BlockUpdate ( bool blocked )

Blocks the update of the viewer.

Returns true if the update was already blocked, otherwise false. While the update is blocked, the state changes are recorded but the render windows are not updated and no signals are sent out. The render windows are updated and the "pending" signals are sent out when the update is unblocked. The purpose of this function is to avoid unnecessary updates and signals when a serious of operations needs to be performed on the viewer as a single atomic unit, e.g. changing layout and setting positions. After the required state of the viewer is set, the previous blocking state should be restored.

Pattern of usage:

bool updateWasBlocked = viewer->BlockUpdate(true);
... set the required state ...
viewer->BlockUpdate(updateWasBlocked);

bool niftk::SingleViewerWidget::ContainsRenderWindow ( QmitkRenderWindow * renderWindow ) const

Returns true if the widget is fully created and contains the given render window, and false otherwise.

void niftk::SingleViewerWidget::CursorPositionBindingChanged ( bool bound )

signal

void niftk::SingleViewerWidget::FitToDisplay ( double scaleFactor = 0.0 )

Moves the displayed regions to the centre of the 2D render windows and scales them, optionally. If no scale factor is given or the specified value is 0.0 then the maximal zooming is applied, using which each region fits into their window, also considering whether the scale factors are bound across the windows. If a positive scale factor is given then the scale factor of each render window is set to the specified value. If the specified scale factor is -1.0 then no scaling is applied. The regions are moved to the middle of the render windows in each cases.

A double click can result in up to three CursorPositionChanged events, depending on how many coordinates of the selected position have changed, if any.
