Split pane displays two components in two display zones at a time. If you want to display components in multiple display zones at the same time, you must make
Use multiple split pane. Jsplitpane provides two constants for you to determine whether horizontal or vertical segmentation is required. The two constants are: horizontal_spit,
Vertical_split. In addition to the two important constants, jsplitpane also provides many class constants for you to use. We will introduce common class constants in the following example.
For other information, see Java API.
Jsplitpane constructor:
Jsplitpane (): Creates a new jsplitpane, which contains two default buttons and arranged horizontally. This does not support the continuous layout function.
Jsplitpane (INT neworientation): Creates a specified horizontal or vertical cutting jsplitpane, but does not have the continuous layout function.
Jsplitpnae (INT neworientation, Boolean newcontinuouslayout): Creates a jsplitpane with a specified horizontal or vertical cut and specifies whether
Has the continuous layout function.
Jsplitpane (INT neworientation, Boolean newcontinuouslayout, component newleftcomponent, component newrightcomponent ):
Create a jsplitpane for horizontal or vertical cutting, specify the components to be displayed in the display area, and set whether to continue
Layout function.
Jsplitpane (INT neworientation, component newleftcomponent, component newrightcomponent ):
Create a jsplitpane with a specified horizontal or vertical cutting and specify the components to be displayed in the display area. However, the continuous layout function is not available.
.
The continuous layout mentioned above indicates whether the components in the window dynamically change the size when you drag the separator line of the cut panel.
. Newcontinuouslayout is a Boolean value. If it is set to true, the component size will be changed along with the drag of the separator line;
If it is set to false, the component size is determined only when the separator line is stopped. You can also use the setcontinuouslayout () method in jsplitpane to set this project.
