Functions ¶
func SubWidgetSize ¶
func SubWidgetSize(w IVerticalPadding, size gowid.IRenderSize, focus gowid.Selector, app gowid.IApp) gowid.IRenderSize
Types ¶
type IVerticalPadding ¶
type IVerticalPadding interface {
Align() gowid.IVAlignment
Height() gowid.IWidgetDimension
}
type IWidget ¶
type IWidget interface {
gowid.ICompositeWidget
IVerticalPadding
}
type Widget ¶
type Widget struct {
gowid.IWidget

gowid.SubWidgetCallbacks
// contains filtered or unexported fields
}
Widget wraps a widget and aligns it vertically according to the supplied arguments. The wrapped widget can be aligned to the top, bottom or middle, and can be provided with a specific height in #lines.
func New ¶
func New(inner gowid.IWidget, alignment gowid.IVAlignment, height gowid.IWidgetDimension) *Widget
func (*Widget) Align ¶
func (w *Widget) Align() gowid.IVAlignment
func (*Widget) Height ¶
func (w *Widget) Height() gowid.IWidgetDimension
func (*Widget) OnSetAlign ¶
func (w *Widget) OnSetAlign(f gowid.IWidgetChangedCallback)
func (*Widget) OnSetHeight ¶
func (w *Widget) OnSetHeight(f gowid.IWidgetChangedCallback)
func (*Widget) RemoveOnSetAlign ¶
func (*Widget) RemoveOnSetHeight ¶
func (*Widget) RenderSize ¶
func (w *Widget) RenderSize(size gowid.IRenderSize, focus gowid.Selector, app gowid.IApp) gowid.IRenderBox
func (*Widget) SubWidgetSize ¶
func (w *Widget) SubWidgetSize(size gowid.IRenderSize, focus gowid.Selector, app gowid.IApp) gowid.IRenderSize
SubWidgetSize returns the size that will be passed down to the subwidget's Render(), based on the size passed to the current widget. If this widget is rendered in a Flow context and the vertical height specified is in Units, then the subwidget is rendered in a Box content with Units-number-of-rows. This gives the subwidget an opportunity to render to fill the space given to it, rather than risking truncation. If the subwidget cannot render in Box mode, then wrap it in a FlowToBoxWidget first.
