The table layout manager places components in a grid of columns and rows, allowing specified components to span multiple columns or rows. Not all columns/rows necessarily have the same width/height.
A column/row can be given an absolute size in pixels, a percentage of the available space, or it can grow and shrink to fill the remaining space after other columns/rows have been resized.
Use the column and row headers to insert or delete columns/rows and change column/row properties.
is open source and not
part of the standard Java
distribution. You must ship an additional library with your
application. JFormDesigner includes
folder. For more documentation and tutorials, visit tablelayout.java.net.
The API documentation is also available here: doc.formdev.com/tablelayout/.
IDE plug-ins: If you use TableLayout the first time, the JFormDesigner IDE plug-in ask you whether it should copy the required library (and its source code and documentation) to the IDE project and add it to the classpath of the IDE project.
JFormDesigner extends the original TableLayout with following features:
- Default component alignment
Allows you to specify a default alignment for components within columns/rows. This is very useful for columns with right aligned labels because you specify the alignment only once for the column and all added labels will automatically aligned to the right.
Layout manager properties¶
A container with this layout manager has following layout manager properties:
|horizontal gap||The horizontal gap between components.||5|
|vertical gap||The vertical gap between components.||5|
Each column and row has its own properties. Use the column and row headers to change column/row properties.
Tip: The column/row context menu allows you to alter many of these options for multi-selections.
Layout constraints properties¶
A component contained in a container with this layout manager has following layout constraints properties:
|grid x||Specifies the component's horizontal grid origin (column index).||0|
|grid y||Specifies the component's vertical grid origin (row index).||0|
|grid width||Specifies the component's horizontal grid extend (number of columns).||1|
|grid height||Specifies the component's vertical grid extend (number of rows).||1|
|h align||The horizontal alignment of the component within its cell. Possible values: DEFAULT, LEFT, CENTER, RIGHT and FILL.||DEFAULT|
|v align||The vertical alignment of the component within its cell. Possible values: DEFAULT, TOP, CENTER, BOTTOM and FILL.||DEFAULT|
In contrast to the TableLayoutConstraints API, which uses [column1,row1,column2,row2] to specify the location and size of a component, JFormDesigner uses the usual [x,y,width,height] notation.
Tip: The component context menu allows you to alter the alignment for multi-selections.
