I struggled for about half a day trying to get some sort of menu system in AngularJS working. To make the text fields wide enough to fill their display areas horizontally without changing their heights, in the Fill combobox in the Property Sheet area, select Horizontal. Point getLayoutOrigin Determines the origin of the layout area, in the graphics coordinate space of the target container. Since the preferred size of the combobox is smaller than the size of the corresponding cell, the GridBagLayout places the component into the center of the cell by default.

The components are now placed in accordance with the target layout. Place a component at cell location 1,1 GridBagLayout does not allow components to span multiple rows unless the component is in the leftmost column or you have specified positive gridx and gridy values for the component. We recommend specifying the gridx and gridy gridbaglaayout for each component; this tends to result in more predictable layouts.

GridBagLayout doesn’t allow components to span multiple rows gridbaglsyout the component is in the leftmost column or you’ve specified positive gridx and gridy values for the component. Similarly, not all columns necessarily have the same width. Moving You can move components using simple drag and drop as desired.


When you enlarge Gridbaglayokt window, the columns grow proportionately. You can download the project that is used as the starting point for this series as a.

Totally awesome tutorial, you really saved my ass here. It allows for easy modification of the most common layout constraints such as AnchorInsetsetc. If we think about it for a while, we can gridbwglayout that not all regions gridbaglaoyut into a grid cell, some regions spread into two cells marked in blue: Point location int x, int y Determines which cell in the layout grid contains the point specified by x, y.

This constraint object holds all the information on how tutoriql component should be displayed. The preferred approach to set constraints on a component is to use the Container. Determines the origin of the layout area, in the graphics coordinate space of the gridbaglayoout container.

Select Horizontal in the Fill combobox and press Enter. During horizontal resizing of the ContactsBasicInitial form in the previous section you have probably noticed that the State combobox moves away from the State label.

External Tools and Services. This method is obsolete and supplied for backwards compatability only; new code should call getMinSize instead. When editing the layout you tutoriao how to use the basic features of the GridBag Customizer.

How to Use GridBagLayout

The GridBag Layout Customizer is one of the most flexible and complex layout managers the Java platform provides. You can move components using simple drag and drop as desired. Positions five components within a container, using weights, fill, and relative positioning. Gridbalgayout must be careful, however, to reset the GridBagConstraints instance variables to their default values when necessary.


Values that are not the default are marked in boldface. The next section discusses constraints in depth, in the context of explaining how the example program works. May 16, at 2: We can make the GridBagLayout make these two blue regions cover more than one cell using the gridWidth and gridHeight constraint. If you are not interested in learning all the details of layout management, you might prefer to use the GroupLayout layout manager combined with a builder tool to lay out your GUI.

Here is a picture of how these values are interpreted in a container that has the default, left-to-right component orientation. If the program didn’t specify the fill, the buttons would be at their natural width, like this: Man, you did a great job on this tutorial.

November 29, at 9: The following discussion assumes that the GridBagLayout controls a container that has a left-to-right component orientation.

SWING – GridBagLayout Class

March 31, at 8: Gridbbaglayout has two components that span multiple columns buttons 4 and 5. Hi, Thanks a lot for the example. Spacing By default, each component has no external padding. Specifying Constraints The following code is typical of what goes in a container that uses a GridBagLayout.
