computeSize

protected org.eclipse.swt.graphics.Point computeSize(Composite composite,
                                                     int wHint,

Description copied from class: Layout

Computes and returns the size of the specified composite's client area according to this layout.

This method computes the minimum size that the client area of the composite must be in order to position all children at their minimum size inside the composite according to the layout algorithm encoded by this layout.

When a width or height hint is supplied, it is used to constrain the result. For example, if a width hint is provided that is less than the minimum width of the client area, the layout may choose to wrap and increase height, clip, overlap, or otherwise constrain the children.

layout

protected void layout(Composite composite,
                      boolean flushCache)

Description copied from class: Layout

Lays out the children of the specified composite according to this layout.

This method positions and sizes the children of a composite using the layout algorithm encoded by this layout. Children of the composite are positioned in the client area of the composite. The position of the composite is not altered by this method.

When the flush cache hint is true, the layout is instructed to flush any cached values associated with the children. Typically, a layout will cache the preferred sizes of the children to avoid the expense of computing these values each time the widget is layed out.

When layout is triggered explicitly by the programmer the flush cache hint is true. When layout is triggered by a resize, either caused by the programmer or by the user, the hint is false.

layout in class Layout

isVertical

public boolean isVertical()

getWeights

public int[] getWeights()

Answer the relative weight of each child in the SashForm. The weight represents the percent of the total width (if SashForm has Horizontal orientation) or total height (if SashForm has Vertical orientation) each control occupies. The weights are returned in order of the creation of the widgets (weight[0] corresponds to the weight of the first child created).

setOrientation

public void setOrientation(boolean vertical)

setWeights

public void setWeights(int[] weights)
