A collection of event patterns.

QwtEventPattern introduces an level of indirection for mouse and keyboard inputs. Those are represented by symbolic names, so the application code can be configured by individual mappings.

  • MouseSelect1
    Qt::LeftButton
  • MouseSelect2
    Qt::RightButton
  • MouseSelect3
    Qt::MidButton
  • MouseSelect4
    Qt::LeftButton + Qt::ShiftButton
  • MouseSelect5
    Qt::RightButton + Qt::ShiftButton

initMousePattern()

Constructor

See also:

MousePatternCode, KeyPatternCode

Set default mouse patterns.

See also:

KeyPatternCode

Set default mouse patterns, depending on the number of mouse buttons

Parameters:

numButtons Number of mouse buttons ( <= 3 )

See also:

MousePatternCode

Compare a key event with an event pattern. A key event matches the pattern when both have the same key value and in the state value the same key flags (Qt::KeyButtonMask) are set.

Parameters:

pattern Index of the event pattern
e Key event

Returns:

true if matches

See also:

mouseMatch()

Compare a key event with an event pattern. A key event matches the pattern when both have the same key value and in the state value the same key flags (Qt::KeyButtonMask) are set.

Parameters:

pattern Key event pattern
e Key event

Returns:

true if matches

See also:

mouseMatch()

Compare a mouse event with an event pattern. A mouse event matches the pattern when both have the same button value and in the state value the same key flags(Qt::KeyButtonMask) are set.

Parameters:

pattern Index of the event pattern
e Mouse event

Returns:

true if matches

See also:

keyMatch()

Compare a mouse event with an event pattern. A mouse event matches the pattern when both have the same button value and in the state value the same key flags(Qt::KeyButtonMask) are set.

Parameters:

pattern Mouse event pattern
e Mouse event

Returns:

true if matches

See also:

keyMatch()

Change one key pattern

Parameters:

pattern Index of the pattern
key Key
state State

See also:

QKeyEvent

Change one mouse pattern

Parameters:

pattern Index of the pattern
button Button
state State
