void BpsPixmapWidget::fitBothEnabled

(

bool

aEnabled

)

[signal]

This signal is emitted when page fitting is enabled or disabled.

Parameters:

[in]

aEnabled

The new state.

void BpsPixmapWidget::fitWidthEnabled

(

bool

aEnabled

)

[signal]

This signal is emitted when width fitting is enabled or disabled.

Parameters:

[in]

aEnabled

The new state.

bool BpsPixmapWidget::isFitBoth

(

)

const

Returns:

True if mode is fit both, width and height.

bool BpsPixmapWidget::isFitWidth

(

)

const

Returns:

True if mode is fit width.

int BpsPixmapWidget::margin

(

)

const

Returns:

Returns the current margin.

qreal BpsPixmapWidget::maxZoom

(

)

const

Returns:

The current maximum zoom factor.

QPixmap BpsPixmapWidget::pixmap

(

)

const

Returns:

The currently displayed pixmap.

void BpsPixmapWidget::setFitBoth

(

bool

aEnable

)

[slot]

Enable/disable fitting the pixmap in both directions.

Enabling all fitting automatically disables width fitting.

Parameters:

[in]

aEnable

True to enable, false to disable page fitting.

void BpsPixmapWidget::setFitWidth

(

bool

aEnable

)

[slot]

Enable/disable fitting the pixmap width into the widget.

Enabling width fitting automatically disables allover fitting.

Parameters:

[in]

aEnable

True to enable, false to disable both fitting.

void BpsPixmapWidget::setMargin

(

int

aMargin

)

Set the margin (pixels) to keep around the pixmap within the widget.

The default margin is 0.

Parameters:

[in]

aMargin

The new margin to set.

void BpsPixmapWidget::setMaxZoom

(

qreal

aZoom

)

Set the maximum zoom factor.

The default maximum zoom factor is 1.0.

Parameters:

[in]

aZoom

The new maximum zoom factor to set.

void BpsPixmapWidget::setPixmap

(

const QPixmap &

aPixmap

)

Set the pixmap to be displayed.

Parameters:

[in]

aPixmap

The pixmap to display.

void BpsPixmapWidget::setZoom

(

qreal

aZoom

)

[slot]

Set the zoom factor, where 1.0 equals 100%.

This function does nothing if both or width fitting is enabled.

Parameters:

[in]

aZoom

The new zoom factor to set.

qreal BpsPixmapWidget::zoom

(

)

const

Get the current zoom factor.

If neither isFitPage() nor isFitWidth() is true, the zoom factor stays constant when resizing the widget.

Returns:

The current zoom factor.

void BpsPixmapWidget::zoomChanged

(

qreal

aZoom

)

[signal]

This signal is emitted when the zoom factor changes.

Parameters:

[in]

aZoom

The new zoom factor.
