Constructor Detail

AlignLayout

public AlignLayout()

Creates an aligner layout with 2 columns, a variable number of rows, and a gap of 5 pixels.

AlignLayout

public AlignLayout(int cols,
                   int hgap,
                   int vgap)

Creates an aligner layout with the specified number of columns and gaps.

Parameters:

cols - the number of columns (should be a multiple of 2)

hgap - the horizontal gap variable

vgap - the vertical gap variable

Throws:

IllegalArgumentException - If the rows and columns are invalid.

Method Detail

getLabelVerticalAlignment

public int getLabelVerticalAlignment(Component child)

Gets the vertical position of a label relative to its control.

Parameters:

child - component

Returns:

number

setLabelVerticalAlignment

public void setLabelVerticalAlignment(Component child,
                                      int align)

Sets the vertical position of a label relative to its control.

Parameters:

child - component

align - TOP, MIDDLE (default), or BOTTOM.

Throws:

IllegalArgumentException - If an invalid value is set

getResizeWidth

public boolean getResizeWidth(Component child)

Gets the component's RezizeWidth value.

Parameters:

child - component

Returns:

flag

setResizeWidth

public void setResizeWidth(Component child,
                           boolean v)

Sets whether the control should be resized horizontally to its parent's right edge if it is in the last column (default: false).

Parameters:

child - component

v - flag

getResizeHeight

public boolean getResizeHeight(Component child)

Gets the component's RezizeHeight value.

Parameters:

child - component

Returns:

flag

setResizeHeight

public void setResizeHeight(Component child,
                            boolean v)

Sets whether the control should be resized vertically to the height of the largest component in its row (default: false). This value is ignored for labels (the components in odd columns).

Parameters:

child - component

v - flag

isLabel

protected boolean isLabel(int col)

setBounds

protected void setBounds(int pos,
                         int row,
                         int col,
                         Component comp,
                         int x,
                         int y,
                         int col_width,
                         int row_height)
