Java JPanel GridBagLayout未对齐垂直对象
以下代码的问题在于,它将Java JPanel GridBagLayout未对齐垂直对象,java,swing,jpanel,gridbaglayout,Java,Swing,Jpanel,Gridbaglayout,以下代码的问题在于,它将菜单页分成两半,而不是所需的10%到90% TitlePane和ControlPane只是jpanel public class MenuPane extends JPanel { public MenuPane( int width, int height ){ setSize( width, height ); setLayout( new GridBagLayout() ); GridBagConstraints c = new Gr
菜单页
分成两半,而不是所需的10%到90%
TitlePane
和ControlPane
只是jpanel
public class MenuPane extends JPanel {
public MenuPane( int width, int height ){
setSize( width, height );
setLayout( new GridBagLayout() );
GridBagConstraints c = new GridBagConstraints();
c.gridx = 0;
c.gridy = 0;
c.weightx = 0.0d;
c.weighty = 0.1d;
add( new TitlePane( this.getWidth(), (int) (this.getHeight()*c.weighty) ), c );
c.gridx = 0;
c.gridy = 1;
c.weightx = 0.0d;
c.weighty = 0.9d;
add( new ControlPane( this.getWidth(), (int) (this.getHeight()*c.weighty) ), c );
}
}
我真的不知道代码是做什么的,但是组件只有在组件显示在可见的GUI上时才有大小。因此,getWidth()/Height()方法将返回0
如果希望零部件以90/10的比例显示,则初始首选尺寸也必须以90/10的比例显示。权重因子仅在调整组件大小时适用
我不知道您的ControlPane代码是什么样子,因此我无法建议进行具体更改
您可以尝试使用专门为此设计的。当您将组件添加到容器中时,您只需要指定定量,它将从此处管理大小
add( new TitlePane( this.getWidth(), (int) (this.getHeight()*c.weighty) ), c );
