static WidgetScrollBoxPtr create ( const Ptr<Gui> & gui, int x = 0, int y = 0 ) #
Constructor. Creates a box with scrolling based on given parameters and adds it to the specified GUI.Arguments
- const Ptr<Gui> & gui - GUI, to which the new box will belong.
- int x - Horizontal space between the widgets in the box and between them and the box border. This is an optional parameter.
- int y - Vertical space between the widgets in the box and between them and the box border. This is an optional parameter.
static WidgetScrollBoxPtr create ( int x = 0, int y = 0 ) #
Constructor. Creates a box with scrolling based on given parameters and adds it to the Engine GUI.Arguments
- int x - Horizontal space between the widgets in the box and between them and the box border. This is an optional parameter.
- int y - Vertical space between the widgets in the box and between them and the box border. This is an optional parameter.
void setBorder ( int border ) #
Sets a flag indicating if a one-pixel border is rendered around the widget content (in a shape of a box). The default is 1 (use a border).Arguments
- int border - Positive number to enable a border, 0 to disable it.
int getBorder ( ) const#
Returns a flag indicating if a one-pixel border is rendered around the widget content (in a shape of a box). The default is 1 (use a border).Return value
Positive number if a border is enabled; otherwise, 0.void setHScrollEnabled ( bool enabled ) #
Sets a value indicating if horizontal scrolling is enabled.Arguments
- bool enabled - Positive number to enable horizontal scrolling, 0 to disable it.
bool isHScrollEnabled ( ) const#
Returns a value indicating if horizontal scrolling is enabled.Return value
Positive number if scrolling is enabled; otherwise, 0.int getHScrollFrameSize ( ) const#
Returns the width of the currently visible area.Return value
Width of the visible area in pixels.void setHScrollHidden ( WidgetScrollBox::SCROLL_RENDER_MODE hidden ) #
Sets a flag indicating if a horizontal scroll bar is hidden, disabled or always rendered.Arguments
- WidgetScrollBox::SCROLL_RENDER_MODE hidden - Hide mode:
- 0 to always render a scroll bar.
- 1 to automatically hide a scroll bar, if necessary. If the container area is big enough to show all elements, the scroll bar is not rendered. And vice versa, if not all elements can be shown at once, a scroll bar is rendered.
- 2 to always hide a scroll bar. In this mode, scroll bar bounds, though a bar itself is not rendered, are still taken into account when the widget bounds are calculated.
- 3 to always hide a scroll bar and not to add scroll bar size when calculating widget bounds.
WidgetScrollBox::SCROLL_RENDER_MODE getHScrollHidden ( ) const#
Returns a flag indicating if a horizontal scroll bar is hidden, disabled or always rendered.Return value
Hide flag:- 0 if a scroll bar is always rendered.
- 1 if a scroll bar is automatically hidden when necessary. For example, if the container area is big enough to show all elements, the scroll bar is not rendered. And vice versa, if not all elements can be shown at once, a scroll bar is rendered.
- 2 if a scroll bar is always hidden. In this mode, scroll bar bounds, though a bar itself is not rendered, are still taken into account when the widget bounds are calculated.
- 3 if a scroll bar is always hidden and its size is not added to widget bounds.

Sets a position (and also the size) of the horizontal scroller. That is, it sets the width of the currently invisible area that determines the size of the slider.Arguments
- int value - Position of the scroller. The minimum value is 0, the maximum value is the difference between the object width and the frame width.

- int r - Right-side padding in pixels.
- int t - Top padding in pixels.
- int b - Bottom padding in pixels.
