layout back to summary

layout	back to summary
protected void layout(int width, int height) Overrides javax.swing.text.FlowView.layout. Lays out the children. If the layout span has changed, the rows are rebuilt. The superclass functionality is called after checking and possibly rebuilding the rows. If the height has changed, the `preferenceChanged` method is called on the parent since the vertical preference is rigid. Parameters width:int the width to lay out against >= 0. This is the width inside of the inset area. height:int the height to lay out against >= 0 (not used by paragraph, but used by the superclass). This is the height inside of the inset area.

protected void layout(int width, int height)

Overrides javax.swing.text.FlowView.layout.

Lays out the children. If the layout span has changed, the rows are rebuilt. The superclass functionality is called after checking and possibly rebuilding the rows. If the height has changed, the preferenceChanged method is called on the parent since the vertical preference is rigid.

Parameters

width:int: the width to lay out against >= 0. This is the width inside of the inset area.
height:int: the height to lay out against >= 0 (not used by paragraph, but used by the superclass). This is the height inside of the inset area.

nextTabStop back to summary

nextTabStop	back to summary
public float nextTabStop(float x, int tabOffset) Overrides javax.swing.text.ParagraphView.nextTabStop. Implements javax.swing.text.TabExpander.nextTabStop. Returns the next tab stop position given a reference position. This view implements the tab coordinate system, and calls `getTabbedSpan` on the logical children in the process of layout to determine the desired span of the children. The logical children can delegate their tab expansion upward to the paragraph which knows how to expand tabs. `LabelView` is an example of a view that delegates its tab expansion needs upward to the paragraph. This is implemented to try and locate a `TabSet` in the paragraph element's attribute set. If one can be found, its settings will be used, otherwise a default expansion will be provided. The base location for tab expansion is the left inset from the paragraphs most recent allocation (which is what the layout of the children is based upon). Parameters x:float the X reference position tabOffset:int the position within the text stream that the tab occurred at >= 0. Returns:float the trailing end of the tab expansion >= 0 See Also `TabSet`, `TabStop`, `LabelView`

public float nextTabStop(float x, int tabOffset)

Overrides javax.swing.text.ParagraphView.nextTabStop.

Implements javax.swing.text.TabExpander.nextTabStop.

Returns the next tab stop position given a reference position. This view implements the tab coordinate system, and calls getTabbedSpan on the logical children in the process of layout to determine the desired span of the children. The logical children can delegate their tab expansion upward to the paragraph which knows how to expand tabs. LabelView is an example of a view that delegates its tab expansion needs upward to the paragraph.

The base location for tab expansion is the left inset from the paragraphs most recent allocation (which is what the layout of the children is based upon).

Parameters

x:float: the X reference position
tabOffset:int: the position within the text stream that the tab occurred at >= 0.

Returns:float

the trailing end of the tab expansion >= 0
