java - 代号一工具栏高度

Question

我在获取工具栏的高度时遇到了问题。

添加组件前高度为“0”，添加组件后结果相同。

那么，有没有办法得到真正的工具栏高度？

btnCnt = new Container();
btnCnt.setUIID(null);
btnCnt.addComponent(btnBack);
btnCnt.addComponent(btnHome);
btnCnt.addComponent(btnExit);

currentForm.setToolBar(homeToolBar);
currentForm.addCommand(SideLogoCommand);
homeToolBar.addCommandToSideMenu(MenuCommand);
homeToolBar.setTitleComponent(btnLogo);

Container commandCnt = new Container(new BorderLayout());
commandCnt.addComponent(BorderLayout.EAST, btnCnt);
commandCnt.setUIID(null);
commandCnt.setPreferredH(homeToolBar.getHeight());
stateMachine.findCntHomeV2Header(currentForm).removeAll();
stateMachine.findCntHomeV2Header(currentForm).repaint();
stateMachine.findCntHomeV2Header(currentForm).addComponent(commandCnt);

Answer 1

您需要的是 setSameHeight() 而不是 setPrefferedH()。

setPrefferedH() 已弃用。

如果您仍想这样做，请使用 homeToolBar.getPreferredH() 而不是 homeToolBar.getHeight()

btnCnt = new Container();
btnCnt.setUIID(null);
btnCnt.addComponent(btnBack);
btnCnt.addComponent(btnHome);
btnCnt.addComponent(btnExit);

currentForm.setToolBar(homeToolBar);
currentForm.addCommand(SideLogoCommand);
homeToolBar.addCommandToSideMenu(MenuCommand);
homeToolBar.setTitleComponent(btnLogo);


Container commandCnt = new Container(new BorderLayout());
commandCnt.addComponent(BorderLayout.EAST, btnCnt);
commandCnt.setUIID(null);
Component.setSameHeight(homeToolBar, commandCnt);
stateMachine.findCntHomeV2Header(currentForm).removeAll();
stateMachine.findCntHomeV2Header(currentForm).repaint();
stateMachine.findCntHomeV2Header(currentForm).addComponent(commandCnt);
