A Builder for Swing GridBagConstraints to ease the creation of Gridbag-Layouts. Instead of having a long parameter list of the GridBagConstraints constructor the builder provides named methods.
Construct the builder with default values
xPos = 0;
yPos = 0;
width = 1;
height = 1;
weightX = 0;
weightY = 0;
anchor = GridBagConstraints.WEST;
fill = GridBagConstraints.NONE;
insets = new Insets(0, 0, 0, 0);
paddingX = 0;
paddingY = 0;or use constructor with Java GridBagContraintsBuilder(GridBagConstraints initialConfiguration) to set own default values for reset.
There are two approches to place the compontents on the grid:
1.) Explicit setting x and y pos:
GridBagContraintsBuilder gbb = new GridBagContraintsBuilder();
mainPanel.add(firstRowFirstCol, gbb.x(0).y(0).insets(5).buildAndReset());
mainPanel.add(firstRowSecondCol, gbb.x(1).y(0).insets(5).rowRemainder().buildAndReset());
mainPanel.add(secondRowFirstCol, gbb.x(0).y(1).insets(5).buildAndReset());2.) Working column by column and row by row
GridBagContraintsBuilder gbb = new GridBagContraintsBuilder();
mainPanel.add(firstRowFirstCol, gbb.x(0).y(0).insets(5).build());
mainPanel.add(firstRowSecondCol, gbb.newCol().insets(5).rowRemainder().build());
mainPanel.add(secondRowFirstCol, gbb.newRow().insets(5).build());Example:
GridBagContraintsBuilder gbb = new GridBagContraintsBuilder();
mainPanel.add(firstRowFirstCol, gbb.x(0).y(0).insets(5).buildAndReset());
mainPanel.add(firstRowSecondCol, gbb.x(1).y(0).insets(5).rowRemainder().buildAndReset());
mainPanel.add(secondRowFirstCol, gbb.x(0).y(1).insets(5).buildAndReset());
mainPanel.add(secondRowSecondCol, gbb.x(1).y(1).insets(5).buildAndReset());
mainPanel.add(secondRowThirdCol, gbb.x(2).y(1).insets(5).buildAndReset());
mainPanel.add(thirdRowFirstCol, gbb.x(0).y(2).insets(5).buildAndReset());
mainPanel.add(thirdRowSecondCol, gbb.x(1).y(2).insets(5).expandHorizontal().rowRemainder().buildAndReset());
mainPanel.add(fourthRowFirstCol, gbb.x(0).y(3).insets(5).buildAndReset());
mainPanel.add(fourthRowSecondCol, gbb.x(1).y(3).insets(5).south().buildAndReset());
mainPanel.add(fourthRowThirdCol, gbb.x(2).y(3).insets(5).expandBoth().buildAndReset());
mainPanel.add(fifthRowFirstCol, gbb.x(0).y(4).insets(5).buildAndReset());
mainPanel.add(fifthRowSecondCol, gbb.x(1).y(4).insets(5).buildAndReset());
mainPanel.add(fifthRowThirdCol, gbb.x(2).y(4).insets(5).east().buildAndReset());
