Detailed Description

This class represents the MILX Qt Render Window Display object using QVTK.

Author: Shekhar S. Chandra, 2013

This is a base class for VTK windows. It encapsulates all the basic properties of VTK displays. You should use the milxQtModel milxQtImage etc. classes instead of this class.

Usage Examples: Displaying a sphere

vtkSmartPointer<vtkSphereSource> sphere = vtkSmartPointer<vtkSphereSource>::New();
    sphere->SetThetaResolution(32);
    sphere->SetPhiResolution(32);
    sphere->SetRadius(10.0);
    sphere->Update();
vtkSmartPointer<vtkPolyDataMapper> mapper = vtkSmartPointer<vtkPolyDataMapper>::New();
    mapper->SetInputConnection(sphere->GetOutputPort());
vtkSmartPointer<vtkActor> actor = vtkSmartPointer<vtkActor>::New();
    actor->SetMapper(mapper);
renderWin->setName("Sphere");
    renderWin->AddActor(actor);
    renderWin->generateRender();
    renderWin->show();

Notice how in the above example requires a lot of VTK code. This is further reduced by using milxQtModel, when displaying models.

The rendering is encapsulated within a milxQtWindow widget.

Definition at line 656 of file milxQtRenderWindow.cpp.

◆ addModelActor

void milxQtRenderWindow::addModelActor ( vtkSmartPointer< vtkActor > mdlActor )

slot

Directly add model actor to generic view.

Definition at line 1957 of file milxQtRenderWindow.cpp.

◆ contextMenuSystem()

void milxQtRenderWindow::contextMenuSystem ( bool context )

Disable/enable context menu system, should be on by default otherwise VTK will steal all right click events.

Also sets up render window object and widgets.

WARNING: Use this caarefully and straight after creation.

Force Stereo Render off

Force Error reporting

Performance

Unbind the right mouse button events as Qt uses context menu.

Definition at line 91 of file milxQtRenderWindow.cpp.

slot

Generate the render so it is ready for display. Should be called before showing the window.

Consider using refresh() or reset() to regenerate the view rather than this member for performance reasons. You should only need to call this member once.

Create the renderer for the actor

Create the Render Window with renderer

Resize Window

◆ GetDataSet()

virtual vtkDataSet* milxQtRenderWindow::GetDataSet ( )

inlinevirtual

Get the data, Implement in derived class that uses data derived from vtkDataSet, like vtkPolyData or vtkImageData.

Useful for getting scalar range etc.

Reimplemented in milxQtImage, milxQtModel, and milxQtPlot.

Definition at line 307 of file milxQtRenderWindow.h.

◆ getDefaultOrientation

milxQtRenderWindow::getDefaultOrientation ( )

inlineslot

Get the orientation mode to one of the supported standards.

0-Radiological: Feet first view 1-Neurological: Head first view

Definition at line 556 of file milxQtRenderWindow.h.

◆ importFrom

void milxQtRenderWindow::importFrom ( milxQtRenderWindow * windowToImportFrom )

slot

Import actors/scene directly from another renderwindow.

Here we use the Qt signals and slots directly as it was found that the VTK-Qt connector caused problems with the image actors.

< transfer model actor to current model

Keep UI responsive

◆ openModelUsingQt

bool milxQtRenderWindow::openModelUsingQt	(	const QString	filename,
		vtkSmartPointer< vtkPolyData > &	data
	)

slot

Opens a model file using Qt file objects, which can be a Wavefront Object file (*.obj) only. This member is intended to be used with the Qt resource system.

Only supports triangulated meshes atm. This is useful for support for 'qrc:/' and ':/' paths, hence allowing meshes to be stored within the executable binary. Returns true if successful.

tri's only

Todo:: generalise

Definition at line 1532 of file milxQtRenderWindow.cpp.

◆ removeImageActor

void milxQtRenderWindow::removeImageActor ( vtkSmartPointer< vtkImageActor > imgActor )

slot

Directly remove image actor from generic view.

< remove model actor to current render

Definition at line 837 of file milxQtRenderWindow.cpp.

◆ removeModelActor

void milxQtRenderWindow::removeModelActor ( vtkSmartPointer< vtkActor > mdlActor )

slot

Directly remove model actor from generic view.

< remove model actor to current render

Definition at line 640 of file milxQtRenderWindow.cpp.

◆ scaleDisplay

milxQtRenderWindow::scaleDisplay ( const bool forceDisplay = false )

inlinevirtualslot

Toggles the scale bar display.

forceDisplay Boolean is to overide possible previous settings and display bar.

Definition at line 660 of file milxQtRenderWindow.h.

◆ setDefaultOrientation

milxQtRenderWindow::setDefaultOrientation ( int orientMode )

inlineslot

Change orientation mode to one of the supported standards. Default: Radiological.

0-Radiological: Feet first view 1-Neurological: Head first view

Definition at line 565 of file milxQtRenderWindow.h.

◆ setView

void milxQtRenderWindow::setView ( int viewMode )

slot

Change view to view mode identified by number. 0-axial, 1-coronal, 2-sagittal.

Saves the camera details to internal variables that can be restore anytime with loadView().

Definition at line 483 of file milxQtRenderWindow.cpp.

◆ updateCoords

void milxQtRenderWindow::updateCoords ( vtkObject * obj )

virtualslot

Picks the coordinates and pixel value from the current mouse position in the window.

Get interactor

Get event position Code initial by Mark Wyszomierski 2003-2007 @ devsample Modified by Shekhar Chandra Do the pick. It will return a non-zero value if we intersected the image.
