findClicked()

virtual GDrawerHit * GView::findClicked ( const QPointF &  , GKHitModifier  = eAll, bool  = false  )

virtual

Find an object (and only object) in where the point dp its interior to it. The modifier can be used to look only on:

• select objects
• unselected objects
• all the objects, selected or unselected

Also an additional parameter to extend the search to non_editable layers can be specified.

This method stops when it founds the first suitable object. On a 2D View the layer order is used (top layers are used first).

Reimplemented in G2DView.

findClickedByType()

virtual GDrawerHit * GView::findClickedByType ( const QPointF &  p, GKType *  type, GKHitModifier  = eAll, bool  = false  )

virtual

Find an object (and only object) of type "type" in where the point dp its interior to it. The modifier can be used to look only on:

• select objects
• unselected objects
• all the objects, selected or unselected

Also an additional parameter to extend the search to non_editable layers can be specified.

On a 2D View the layer order is used (top layers are used first).

findDrawer()

virtual GDrawer * GView::findDrawer ( const GKGeoObject *  key ) const

virtual

Find a drawer in this view. Can return None

getDrawers()

virtual const QHash< GKGeoObject *, GDrawer * > & GView::getDrawers ( ) const

pure virtual

Returns the list of all the drawers in this view

getFilter()

GKProblemNet * GView::getFilter

(

)

const

getGeoModel()

GKGeoModel & GView::getGeoModel

(

)

getGui()

GGui & GView::getGui

(

)

getMode()

GKViewMode * GView::getMode

(

)

const

getTimeContext()

GKContext & GView::getTimeContext

(

)

Time context for this view: it uses only Now to know what time dependad information must be displayed on this view.

if()

GView::if ( base  )

inline

References base, GKSystem::getSystem(), and sipType.

invalidate()

virtual void GView::invalidate ( )

virtual

Marks this view as invalid forcing a redraw.

Reimplemented in G2DView.

inverseSelection()

virtual void GView::inverseSelection ( )

virtual

Inverses the current selection. Objects selected will be unselected and objects unselecteds will be selected. Note that a drawer can refuse a selection, so this command will not affected it.

Reimplemented in G2DView.

multiFindClicked()

virtual QVector< GDrawerHit * > GView::multiFindClicked ( const QPointF &  , GKHitModifier  , bool  = false  )

virtual

Find all the objects in where the point dp its interior to it. The modifier can be used to look only on:

• select objects
• unselected objects
• all the objects, selected or unselected

Also an additional parameter to extend the search to non_editable layers can be specified.

Reimplemented in G2DView.

panToObject()

virtual void GView::panToObject ( const GKGeoObject *  )

virtual

Makes the object key visible and centered in the view.

Reimplemented in G2DView.

populate()

virtual void GView::populate ( )

pure virtual

Create drawers for all the objects in the geo model and add them to the view.

removeDrawer()

virtual GDrawer * GView::removeDrawer ( const GKGeoObject *  key )

pure virtual

Removes a drawer from the list of drawers for a specific object and returns it. The drawer is not deleted.

saveSnapshot()

virtual bool GView::saveSnapshot ( const QString &  , const char *  , GKBBox  , int  = -1, int  = -1, bool  = true  )

virtual

Saves a snapshot of this view

• If area is undefined takes a snap of the whole network
• If area with and heifg are 0 takes a snap of the current view area
• If the area is valid it takes a snap fo the area.
  

Reimplemented in G2DView.

screen2World()

virtual GKPoint GView::screen2World ( const QPointF &  ) const

pure virtual

Implemented in G2DView.

selectAll()

virtual void GView::selectAll ( )

virtual

Select all the geo objects. This command uses the drawers in this view in order to know which objects can be selected. Note that a drawer can make non selectable an object and that this setting is per view and not per model.

Reimplemented in G2DView.

setFilter()

virtual void GView::setFilter ( GKProblemNet *  )

virtual

Reimplemented in G2DView.

setFloatingString()

virtual void GView::setFloatingString ( const QString &  , const GKPoint &  , GKFloatingStringRelativePos  = eRight  )

virtual

Shows a text over the view objects.

setMode()

virtual void GView::setMode ( GKViewMode *  )

virtual

setTimeContext()

void GView::setTimeContext

(

const GKContext &

)

Sets the time context for this view: it uses only Now to know what time dependad information must be displayed on this view.
