How to Use GridBagLayout

If the container is given a size that is smaller or bigger than the prefered size, then any space is distributed according to the GridBagContainer weights. Currently you have JavaScript disabled.

If you enlarge the window as shown in the following figure, you’ll notice that the bottom row, which contains Button 5, gets all the new vertical space. December 13, at 9: Toolbar A toolbar with five buttons is located above the Grid area. Click here for instructions on how to enable JavaScript in your browser.

The following code is typical of what goes in a container that uses a GridBagLayout. Weight X and weight Y should be set to 1. The preferred approach to set constraints on a component is to use the Container.

In this short tutorial, you designed a simple form. Essentially, the GridBagLayout places components in rectangles cells in a grid, and then uses the components’ preferred sizes to determine how big the cells should be. Could you please help me with this.


In this tutorial the GridBagLayout is already set. This section will be changed to use standard API tables. To create a layout like shown in the picture below, move the components from columns 2 to 11 as follows: If no component managed by the GridBagLayout had weightx set, then when the components’ container was made wider, the components would stay clumped together in the center of the container, like this:.

All the components in the pane container are as wide as possible, given the cells that they occupy. This lesson covers writing layout code by hand, which can be challenging.

The labels are anchored to the left. If you find some of the text fields on the right are collapsing, add some column width via the integer parameter when constructing text fields:. Adding functionality to the GUI is out of its scope. It is now possible to create area charts in Iceberg Charts that look something like this: You can download the project that is used as the starting point for this series as a.

The new horizontal space is split evenly among all the columns. Tutoorial Customizer places components in a grid of rows and columns, allowing specified components to span multiple rows or columns.

The Tutorial’s examples used to specify the constraints object a different way, which you might see in other programs as well. The actual value of these components’ weightx is unimportant. Just before each component is added to the container, the code sets or resets to default values the appropriate instance variables in the GridBagConstraints object. This is because only button 5 has weighty greater than zero.


These constraints specify the number of cells the component uses, not the number of pixels it uses. In the displayed dialog box, change Top: Point getLayoutOrigin Determines the origin of the layout area, in the graphics coordinate space of the target container. We do this by setting the gridWidth property to two for those fields that we want to stretch over. The following code creates the GridBagLayout and the components it manages.

The following discussion assumes that the GridBagLayout controls a container that has a left-to-right component orientation. Documentation General Java Development.

Previous releases require values named after points of the compass. Returns the maximum dimensions for this layout given the components in the specified target container. Anchoring is tuotrial when the component is smaller than its display area to determine where within the area to place the component.

This method is obsolete and supplied for backwards compatability only; new code should call getLayoutInfo instead.
