Method Detail

getMargin

public final java.awt.Insets getMargin()

getHGap

public final int getHGap()

Returns:

current own value of horizontal gap between columns. If horizontal gap isn't defined then the method returns -1.

getHGapImpl

protected static int getHGapImpl(java.awt.Container container)

Returns:

horizontal gap (if it's defined in the layout) or traverses the container hierarchy to find "inherited" HGAP property. Note, that the method always return positive value.

setHGap

public final void setHGap(int hGap)

Parameters:

hGap - new horizontal gap. If hGap is -1 then own gap is not defined and it should be inherited from parent container.

Throws:

java.lang.IllegalArgumentException - if hGap is less then -1

getVGap

public final int getVGap()

Returns:

current own value of vertical gap between rows. If vertical gap isn't defined then the method returns -1.

getVGapImpl

protected static int getVGapImpl(java.awt.Container container)

Returns:

horizontal gap (if it's defined in the layout) or traverses the container hierarchy to find "inherited" HGAP property. Note, that the method always return positive value.

setVGap

public final void setVGap(int vGap)

Sets new vertical gap between rows

Parameters:

vGap - new vertical gap. If vGap is -1 then own gap is not defined and it should be inherited from parent container.

Throws:

java.lang.IllegalArgumentException - if vGap is less then -1

setMargin

public final void setMargin(java.awt.Insets margin)
