Member Function Documentation

◆ action()

QAction * QgsLayoutViewTool::action ( )

Returns the action associated with the tool or nullptr if no action is associated.

See also: setAction()

Definition at line 109 of file qgslayoutviewtool.cpp.

◆ activate()

void QgsLayoutViewTool::activate ( )

virtual

Called when tool is set as the currently active layout tool.

Overridden implementations must take care to call the base class implementation.

Reimplemented in QgsLayoutViewToolTemporaryKeyZoom, QgsLayoutViewToolTemporaryKeyPan, QgsLayoutViewToolTemporaryMousePan, and QgsLayoutViewToolEditNodes.

Definition at line 120 of file qgslayoutviewtool.cpp.

◆ activated

void QgsLayoutViewTool::activated ( )

signal

Emitted when the tool is activated.

◆ deactivate()

void QgsLayoutViewTool::deactivate ( )

virtual

Called when tool is deactivated.

Overridden implementations must take care to call the base class implementation.

Reimplemented in QgsLayoutViewToolAddNodeItem, QgsLayoutViewToolAddItem, QgsLayoutViewToolZoom, QgsLayoutViewToolPan, QgsLayoutViewToolEditNodes, and QgsLayoutViewToolSelect.

Definition at line 130 of file qgslayoutviewtool.cpp.

◆ deactivated

void QgsLayoutViewTool::deactivated ( )

signal

Emitted when the tool is deactivated.

◆ flags()

QgsLayoutViewTool::Flags QgsLayoutViewTool::flags ( ) const

Returns the current combination of flags set for the tool.

See also: setFlags()

Definition at line 59 of file qgslayoutviewtool.cpp.

◆ ignoredSnapItems()

QList< QgsLayoutItem * > QgsLayoutViewTool::ignoredSnapItems ( ) const

virtual

Returns a list of items which should be ignored while snapping events for this tool.

Reimplemented in QgsLayoutViewToolEditNodes.

Definition at line 48 of file qgslayoutviewtool.cpp.

◆ isClickAndDrag()

bool QgsLayoutViewTool::isClickAndDrag	(	QPoint	startViewPoint,
		QPoint	endViewPoint
	)		const

protected

Returns true if a mouse press/release operation which started at startViewPoint and ended at endViewPoint should be considered a "click and drag".

If false is returned, the operation should be instead treated as just a click on startViewPoint.

Definition at line 31 of file qgslayoutviewtool.cpp.

◆ itemFocused

void QgsLayoutViewTool::itemFocused ( QgsLayoutItem * item )

signal

Emitted when an item is "focused" by the tool, i.e.

it should become the active item and should have its properties displayed in any designer windows.

◆ keyPressEvent()

void QgsLayoutViewTool::keyPressEvent ( QKeyEvent * event )

virtual

Key press event for overriding.

Default implementation does nothing.

Reimplemented in QgsLayoutViewToolAddNodeItem, QgsLayoutViewToolZoom, QgsLayoutViewToolTemporaryKeyZoom, QgsLayoutViewToolEditNodes, and QgsLayoutViewToolSelect.

Definition at line 94 of file qgslayoutviewtool.cpp.

◆ keyReleaseEvent()

void QgsLayoutViewTool::keyReleaseEvent ( QKeyEvent * event )

virtual

Key release event for overriding.

Default implementation does nothing.

Reimplemented in QgsLayoutViewToolZoom, QgsLayoutViewToolTemporaryKeyZoom, and QgsLayoutViewToolTemporaryKeyPan.

Definition at line 99 of file qgslayoutviewtool.cpp.

◆ layout()

QgsLayout * QgsLayoutViewTool::layout ( ) const

Returns the layout associated with the tool.

See also: view()

Definition at line 43 of file qgslayoutviewtool.cpp.

◆ layoutDoubleClickEvent()

void QgsLayoutViewTool::layoutDoubleClickEvent ( QgsLayoutViewMouseEvent * event )

virtual

Mouse double-click event for overriding.

Default implementation does nothing.

Reimplemented in QgsLayoutViewToolEditNodes.

Definition at line 74 of file qgslayoutviewtool.cpp.

◆ layoutMoveEvent()

void QgsLayoutViewTool::layoutMoveEvent ( QgsLayoutViewMouseEvent * event )

virtual

Mouse move event for overriding.

Default implementation does nothing.

Reimplemented in QgsLayoutViewToolAddItem, QgsLayoutViewToolAddNodeItem, QgsLayoutViewToolZoom, QgsLayoutViewToolMoveItemContent, QgsLayoutViewToolPan, QgsLayoutViewToolTemporaryKeyPan, QgsLayoutViewToolTemporaryMousePan, QgsLayoutViewToolEditNodes, and QgsLayoutViewToolSelect.

Definition at line 69 of file qgslayoutviewtool.cpp.

◆ layoutPressEvent()

void QgsLayoutViewTool::layoutPressEvent ( QgsLayoutViewMouseEvent * event )

virtual

Mouse press event for overriding.

Default implementation does nothing. Note that subclasses must ensure that they correctly handle cases when a layoutPressEvent is called without a corresponding layoutReleaseEvent (e.g. due to tool being changed mid way through a press-release operation).

Reimplemented in QgsLayoutViewToolAddItem, QgsLayoutViewToolAddNodeItem, QgsLayoutViewToolZoom, QgsLayoutViewToolMoveItemContent, QgsLayoutViewToolPan, QgsLayoutViewToolEditNodes, and QgsLayoutViewToolSelect.

Definition at line 79 of file qgslayoutviewtool.cpp.

◆ layoutReleaseEvent()

void QgsLayoutViewTool::layoutReleaseEvent ( QgsLayoutViewMouseEvent * event )

virtual

Mouse release event for overriding.

Default implementation does nothing. Note that subclasses must ensure that they correctly handle cases when a layoutPressEvent is called without a corresponding layoutReleaseEvent (e.g. due to tool being changed mid way through a press-release operation).

Reimplemented in QgsLayoutViewToolAddItem, QgsLayoutViewToolAddNodeItem, QgsLayoutViewToolZoom, QgsLayoutViewToolMoveItemContent, QgsLayoutViewToolPan, QgsLayoutViewToolTemporaryKeyZoom, QgsLayoutViewToolTemporaryMousePan, QgsLayoutViewToolEditNodes, and QgsLayoutViewToolSelect.

Definition at line 84 of file qgslayoutviewtool.cpp.

◆ setAction()

void QgsLayoutViewTool::setAction ( QAction * action )

Associates an action with this tool.

When the setLayoutTool method of QgsLayoutView is called the action's state will be set to on. Usually this will cause a toolbutton to appear pressed in and the previously used toolbutton to pop out.

See also: action()

Definition at line 104 of file qgslayoutviewtool.cpp.

◆ setCursor()

void QgsLayoutViewTool::setCursor ( const QCursor & cursor )

Sets a user defined cursor for use when the tool is active.

Definition at line 115 of file qgslayoutviewtool.cpp.

◆ setFlags()

void QgsLayoutViewTool::setFlags ( QgsLayoutViewTool::Flags flags )

protected

Sets the combination of flags that will be used for the tool.

See also: flags()

Definition at line 64 of file qgslayoutviewtool.cpp.

◆ toolName()

QString QgsLayoutViewTool::toolName ( ) const

inline

Returns a user-visible, translated name for the tool.

Definition at line 155 of file qgslayoutviewtool.h.

◆ view()

QgsLayoutView * QgsLayoutViewTool::view ( ) const

Returns the view associated with the tool.

See also: layout()
