virtual

calculate content related size of widget.

Returns: calculated widget size

Reimplemented in ClassifierWidget, EntityWidget, and NoteWidget.

Here is the call graph for this function:

◆ cleanup()

void UMLWidget::cleanup ( )

virtual

Used to cleanup any other widget it may need to delete. Used by child classes. This should be called before deleting a widget of a diagram.

Reimplemented in CombinedFragmentWidget, MessageWidget, and ObjectWidget.

◆ clipSize()

void UMLWidget::clipSize ( )

clip the size of this widget against the minimal and maximal limits.

Here is the call graph for this function:

◆ constrain()

void UMLWidget::constrain	(	qreal &	width,
		qreal &	height
	)

protectedvirtual

Apply possible constraints to the given candidate width and height. The default implementation limits input values to the bounds returned by minimumSize()/maximumSize().

Parameters

width	input value, may be modified by the constraint
height	input value, may be modified by the constraint

Reimplemented in ActivityWidget, and ForkJoinWidget.

Here is the call graph for this function:

◆ constrainMovementForAllWidgets()

void UMLWidget::constrainMovementForAllWidgets	(	qreal &	diffX,
		qreal &	diffY
	)

protectedvirtual

Modifies the value of the diffX and diffY variables used to move the widgets.

It can be overridden to constrain movement of all the selected widgets only in one axis even when the user isn't constraining the movement with shift or control buttons, for example. The difference with moveWidgetBy is that the diff positions used here are applied to all the selected widgets instead of only to m_widget, and that moveWidgetBy, in fact, moves the widget, and here simply the diff positions are modified.

Default behaviour is do nothing.

See also: moveWidgetBy

Parameters

diffX	The difference between current X position and new X position.
diffY	The difference between current Y position and new Y position.

Reimplemented in FloatingTextWidget, MessageWidget, and ObjectWidget.

◆ contextMenuEvent()

Reimplemented from DiagramProxyWidget.

Reimplemented in StateWidget.

Here is the call graph for this function:

◆ deselect()

void UMLWidget::deselect ( QGraphicsSceneMouseEvent * me )

protected

Deselects the widget and removes it from the list of selected widgets.

Parameters

me	The QGraphicsSceneMouseEvent which made the selection.

Here is the call graph for this function:

◆ fixedAspectRatio()

bool UMLWidget::fixedAspectRatio ( ) const

inline

◆ forceUpdateFontMetrics() [1/2]

void UMLWidget::forceUpdateFontMetrics	(	QFont &	font,
		QPainter *	painter
	)

Note: For performance Reasons, only FontMetrics for already used font types are updated. Not yet used font types will not get a font metric and will get the same font metric as if painter was zero. This behaviour is acceptable, because diagrams will always be shown on Display first before a special painter like a printer device is used.

Here is the call graph for this function:

◆ mouseMoveEvent()

void UMLWidget::mouseMoveEvent ( QGraphicsSceneMouseEvent * event )

protectedvirtual

Handles a mouse move event. It resizes or moves the widget, depending on where the cursor is pressed on the widget. Go on reading for more info about this.

If resizing, the widget is resized using UMLWidget::resizeWidget (where specific widget resize constraint can be applied), and then the associations are adjusted. The resizing can be constrained also to a specific axis using control and shift buttons. If one or another is pressed, it's constrained to X axis. If both are pressed, it's constrained to Y axis.

If not resizing, the widget is being moved. If the move is being started, the selection bounds are set (which includes updating the list of selected widgets). The difference between the previous position of the selection and the new one is calculated (taking in account the selection bounds so widgets don't go beyond the scene limits). Then, it's constrained to X or Y axis depending on shift and control buttons. A further constraint is made using constrainMovementForAllWidgets (for example, if the widget that receives the event can only be moved in Y axis, with this method the movement of all the widgets in the selection can be constrained to be moved only in Y axis). Then, all the selected widgets are moved using moveWidgetBy (where specific widget movement constraint can be applied) and, if a certain amount of time passed from the last move event, the associations are also updated (they're not updated always to be easy on the CPU). Finally, the scene is resized, and selection bounds updated.

Parameters

event The QGraphicsSceneMouseEvent event.

Reimplemented from DiagramProxyWidget.

Reimplemented in StateWidget, ObjectWidget, and SignalWidget.

Here is the call graph for this function:

◆ mousePressEvent()

void UMLWidget::mousePressEvent ( QGraphicsSceneMouseEvent * event )

protectedvirtual

Handles a mouse press event. It'll select the widget (or mark it to be deselected) and prepare it to be moved or resized. Go on reading for more info about this.

Widget values and message bar status are saved.

If shift or control buttons are pressed, we're in move area no matter where the button was pressed in the widget. Moreover, if the widget wasn't already selected, it's added to the selection. If already selected, it's marked to be deselected when releasing the button (provided it isn't moved). Also, if the widget is already selected with other widgets but shift nor control buttons are pressed, we're in move area. If finally we don't move the widget, it's selected and the other widgets deselected when releasing the left button.

If shift nor control buttons are pressed, we're facing a single selection. Depending on the position of the cursor, we're in move or in resize area. If the widget wasn't selected (both when there are no widgets selected, or when there're other widgets selected but not the one receiving the press event) it's selected and the others deselected, if any. If already selected, it's marked to be deselected when releasing the button (provided it wasn't moved or resized).

Parameters

event The QGraphicsSceneMouseEvent event.

Reimplemented from DiagramProxyWidget.

Reimplemented in StateWidget, and ObjectWidget.

Here is the call graph for this function:

◆ mouseReleaseEvent()

void UMLWidget::mouseReleaseEvent ( QGraphicsSceneMouseEvent * event )

protectedvirtual

Handles a mouse release event. It selects or deselects the widget and cancels or confirms the move or resize. Go on reading for more info about this. No matter which tool is selected, Z position of widget is updated.

Middle button release resets the selection. Left button release, if it wasn't moved nor resized, selects the widget and deselect the others if it wasn't selected and there were other widgets selected. If the widget was marked to be deselected, deselects it. If it was moved or resized, the document is set to modified if position or size changed. Also, if moved, all the associations are adjusted because the timer could have prevented the adjustment in the last move event before the release. If mouse was pressed in resize area, cursor is set again to normal cursor Right button release if right button was pressed shows the pop up menu for the widget. If left button was pressed, it cancels the move or resize with a mouse move event at the same position than the cursor was when pressed. Another left button release is also sent.

Parameters

event The QGraphicsSceneMouseEvent event.

Reimplemented from DiagramProxyWidget.

Reimplemented in StateWidget.

Here is the call graph for this function:

◆ moveByLocal()

Here is the call graph for this function:

◆ moveEvent()

void UMLWidget::moveEvent ( QGraphicsSceneMouseEvent * me )

protectedvirtual

Overrides the standard operation.

Parameters

me	The move event.

Reimplemented in ObjectWidget.

◆ moveWidgetBy()

void UMLWidget::moveWidgetBy	(	qreal	diffX,
		qreal	diffY
	)

protectedvirtual

Moves the widget to a new position using the difference between the current position and the new position. This method doesn't adjust associations. It only moves the widget.

It can be overridden to constrain movement only in one axis even when the user isn't constraining the movement with shift or control buttons, for example. The movement policy set here is applied whenever the widget is moved, being it moving it explicitly, or as a part of a selection but not receiving directly the mouse events.

Default behaviour is move the widget to the new position using the diffs.

See also: constrainMovementForAllWidgets

Parameters

diffX	The difference between current X position and new X position.
diffY	The difference between current Y position and new Y position.
