Method Summary

String	getText() Returns the text string that the label displays.
boolean	isPreferredSizeSet() Returns true if the preferred size has been set to a non-null value otherwise returns false.
void	setHorizontalAlignment(int pHorizontalAlignment) Sets the horizontal alignment. Possible values are defined in AlignmentConstants.
void	setPreferredSize(IDimension pPreferredSize) Sets the preferred size of this component to a constant value. Subsequent calls to getPreferredSize will always return this value. Setting the preferred size to null restores the default behavior.
void	setText(String pText) Defines the single line of text this component will display.
void	setVerticalAlignment(int pVerticalAlignment) Sets the vertical alignment. Possible values are defined in AlignmentConstants.

Overrides:

setHorizontalAlignment in class QtComponent<QVxLabel>

Parameters:

pHorizontalAlignment - the new vertical alignment

setVerticalAlignment

public void setVerticalAlignment(int pVerticalAlignment)

Sets the vertical alignment. Possible values are defined in AlignmentConstants.
