state Allows to activate (true) or deactivate (false) the filter

void MousePressFilter::setFilterDeactive ( bool  state = false  )  [inline, slot]

state Allows to deactivate (true) or activate (false) the filter

bool MousePressFilter::isChildOf ( QWidget child,
QWidget parent 
) [protected]

child pointer to child widget
parent pointer to parent widget
Return values:
true child points to widget which has parent as parent or grand-parent
false child points to a widget which is not related to parent

bool MousePressFilter::eventFilter ( QObject o,
QEvent *  e 
) [protected]

Reimplemented from base class. Sends out the mousePressedOnExternalWidget() signal if object o points to an object which is not a child widget of any added previously using the addWidget() method. The signal is sent out only once for each event e.

o pointer to QObject
e pointer to QEvent
always returns false
