HeaderLayout
public HeaderLayout()
Constructor HeaderLayout. The default constructor. If you use this constructor, you must manually specify the column weights, and possibly, the fittingHorizontally property value.
-
HeaderLayout
public HeaderLayout(int[] weights)
Constructor HeaderLayout. Construct a HeaderLayout, specifying the column weights. By default, fittingHorizontally is false.- Parameters:
weights- int[] The amount of weight desired for each column in the table. If fittingHorizontally is set to true, the sum of all weights must be 100 and each weight indicates the percentage of the whole table that each column will occupy. If fittingHorizontally is set to false, each weight is the minimum width of the column in pixels. If the table is narrower than can fit all widths, CompositeTable will display a horizontal scroll bar. If the table is wider than can fit all widths, the columns are scaled so that the entire table fills the desired space and the ratios of the column widths remains constant. fittingHorizontally defaults to false.

HeaderLayout
public HeaderLayout(int[] weights, boolean fittingHorizontally)Construct a HeaderLayout, specifying both the weights and the fittingHorizontally property.- Parameters:
weights- int[] The amount of weight desired for each column in the table. If fittingHorizontally is set to true, the sum of all weights must be 100 and each weight indicates the percentage of the whole table that each column will occupy. If fittingHorizontally is set to false, each weight is the minimum width of the column in pixels. If the table is narrower than can fit all widths, CompositeTable will display a horizontal scroll bar. If the table is wider than all minimum column widths, the columns will be scaled so that the ratios of the actual widths remains constant and all columns fit exactly in the available space. fittingHorizontally defaults to false.fittingHorizontally- If true, the weights are interpreted as percentages and the column widths are scaled so that each column occupies the percentage of the total width indicated by its weight. If false, the weights are interpreted as minimum column widths. If the table is narrower than can accommodate those widths, CompositeTable will display a horizontal scroll bar. If the table is wider than all minimum column widths, the columns will be scaled so that the ratios of the actual widths remains constant and all columns fit exactly in the available space.

getWeights
public int[] getWeights()
Description copied from class:AbstractGridRowLayoutMethod getWeights. If isFittingHorizontally, returns an array representing the percentage of the total width each column is allocated or null if no weights have been specified.If !isFittingHorizontally, returns an array where each element is the minimum width in pixels of the corresponding column.
- Overrides:
getWeightsin classAbstractGridRowLayout- Returns:
- the current weights array or null if no weights have been specified.
-
setWeights
public AbstractGridRowLayout setWeights(int[] weights)
Description copied from class:AbstractGridRowLayoutMethod setWeights. If isFittingHorizontally, specifies an array representing the percentage of the total width each column is allocated or null if no weights have been specified.If !isFittingHorizontally, specifies an array where each element is the minimum width in pixels of the corresponding column.
This property is ignored if the programmer has set a layout manager on the header and/or the row prototype objects.
The number of elements in the array must match the number of columns and if isFittingHorizontally, the sum of all elements must equal 100. If either of these constraints is not true, this property will be ignored and all columns will be created equal in width.
- Overrides:
setWeightsin classAbstractGridRowLayout- Parameters:
weights- the weights to use if the CompositeTable is automatically laying out controls.- Returns:
- this
-
