 plQtEngineViewWidget (QWidget *pParent, plQtEngineDocumentWindow *pDocumentWindow, plEngineViewConfig *pViewConfig)
 
plUInt32 GetViewID () const
 Returns the ID of this view.

virtual void SyncToEngine ()
 Sends the redraw message to the engine.
 
void GetCameraMatrices (plMat4 &out_mViewMatrix, plMat4 &out_mProjectionMatrix) const
 
void UpdateCameraInterpolation ()
 Called every frame to move the camera to its current target (focus on selection, etc.)
 
void InterpolateCameraTo (const plVec3 &vPosition, const plVec3 &vDirection, float fFovOrDim, const plVec3 *pNewUpDirection=nullptr, bool bImmediate=false)
 The view's camera will be interpolated to the given coordinates.
 
void SetEnablePicking (bool bEnable)
 If disabled, no picking takes place in this view.
 
void SetPickTransparent (bool bEnable)
 
virtual bool IsPickingAgainstSelectionAllowed () const
 Disabled during drag&drop operations, to prevent picking against the dragged object.
 
void OpenContextMenu (QPoint globalPos)
 Supposed to open a context menu at the given position. Derived classes must implement OnOpenContextMenu and do the actual work there.
 
const plObjectPickingResult & PickObject (plUInt16 uiScreenPosX, plUInt16 uiScreenPosY) const
 Starts a picking operation for the given pixel position in this view. Returns the most recent picking information in the meantime.
 
plResult PickPlane (plUInt16 uiScreenPosX, plUInt16 uiScreenPosY, const plPlane &plane, plVec3 &out_vPosition) const
 Similar to PickObject, but computes the intersection with the given plane instead.
 
void HandleViewMessage (const plEditorEngineViewMsg *pMsg)
 Processes incoming messages from the engine that are meant for this particular view. Mostly picking results.
 
virtual plPlane GetFallbackPickingPlane (plVec3 vPointOnPlane=plVec3(0)) const
 Returns a plane that can be used for picking, when nothing else is available Orthographic views would typically return their projection planes, perspective views may return the ground plane.
 
void TakeScreenshot (const char *szOutputPath) const

Detailed Description

Base class for views that show engine output.

Member Function Documentation

◆ IsPickingAgainstSelectionAllowed()

virtual bool plQtEngineViewWidget::IsPickingAgainstSelectionAllowed ( ) const
inlinevirtual

Disabled during drag&drop operations, to prevent picking against the dragged object.

Reimplemented in plQtSceneViewWidget.

◆ SetEnablePicking()

void plQtEngineViewWidget::SetEnablePicking ( bool bEnable)

If disabled, no picking takes place in this view.

Disabled in views that do not need picking (material asset, particle asset, etc.) and when the mouse is outside a view, to prevent useless picking.

◆ SyncToEngine()

void plQtEngineViewWidget::SyncToEngine ( )
virtual

Sends the redraw message to the engine.

Reimplemented in plQtGameObjectViewWidget, and plQtOrbitCamViewWidget.

◆ UpdateCameraInterpolation()

void plQtEngineViewWidget::UpdateCameraInterpolation ( )

Called every frame to move the camera to its current target (focus on selection, etc.)

Todo
Hard coded up vector

Member Data Documentation

◆ s_FixedResolution

plSizeU32 plQtEngineViewWidget::s_FixedResolution
static

If this is set to a non-zero value, all rendering will use a fixed resolution, instead of the actual window size. This is useful for unit tests, to guarantee a specific output size, to be able to do image comparisons.
