Member Function Documentation

bool te::qt::widgets::AbstractTool::eventFilter ( QObject *  watched, QEvent *  e  )

virtualinherited

Filters events if this object has been installed as an event filter for the watched object.

Parameters

watched	The watched object.
event	The last event sent to watched object.

Note

In your reimplementation of this function, if you want to filter the event out, i.e. stop it being handled further, return true; otherwise return false.

Here, the default implementation looks for QMouseEvents and call the pure virutal methods defined on AbstractTool class, e.g. mousePressEvent().

Reimplemented in te::edit::GeometriesUpdateTool, te::qt::widgets::ZoomKeyboard, and te::qt::widgets::ZoomWheel.

Definition at line 50 of file AbstractTool.cpp.

References te::qt::widgets::AbstractTool::keyPressEvent(), te::qt::widgets::AbstractTool::m_cursor, te::qt::widgets::AbstractTool::m_display, te::qt::widgets::AbstractTool::mouseDoubleClickEvent(), te::qt::widgets::AbstractTool::mouseMoveEvent(), te::qt::widgets::AbstractTool::mousePressEvent(), and te::qt::widgets::AbstractTool::mouseReleaseEvent().

Referenced by te::qt::widgets::ZoomKeyboard::eventFilter(), te::qt::widgets::ZoomWheel::eventFilter(), and te::edit::GeometriesUpdateTool::eventFilter().

bool te::qt::widgets::AbstractTool::keyPressEvent ( QKeyEvent *  e )

virtualinherited

This event handler can be reimplemented in a concrete tool class to receive key press events for the watched object.

Parameters

e	The key event.

Returns

If you want to filter the event out, i.e. stop it being handled further, return true; otherwise return false.

Reimplemented in te::qt::widgets::Measure.

Definition at line 101 of file AbstractTool.cpp.

bool te::qt::widgets::AbstractTool::mouseDoubleClickEvent ( QMouseEvent *  e )

virtualinherited

This event handler can be reimplemented in a concrete tool class to receive mouse double click events for the watched object.

Parameters

e	The mouse event.

Returns

If you want to filter the event out, i.e. stop it being handled further, return true; otherwise return false.

Note

The AbstractTool will also receive mouse press and mouse release events in addition to the double click event. It is up to the developer to ensure that the application interprets these events correctly.

bool te::qt::widgets::AbstractTool::mouseMoveEvent ( QMouseEvent *  e )

virtualinherited

This event handler can be reimplemented in a concrete tool class to receive mouse move events for the watched object.

Parameters

e	The mouse event.

Returns

If you want to filter the event out, i.e. stop it being handled further, return true; otherwise return false.
