[英]Text on JTextField doesn't appear until frame resize
When I click on a button a property frame appears. 当我单击一个按钮时,会出现一个属性框。 Each row has these 3 fields : JLabel name, JTextField value, JSlider slider.
每行具有以下3个字段:JLabel名称,JTextField值,JSlider滑块。 My problem is that when the frame shows, it displays the values correctly, but the text in the JTextField fails to appear until I resize the frame for a bit.
我的问题是,当框架显示时,它会正确显示值,但是JTextField中的文本无法显示,直到我重新调整框架的大小。 I use GridLayout for the JPanel containing the components Any suggestions on what I might do?
我为包含组件的JPanel使用GridLayout关于我可能会做什么的建议?
frame = new JFrame();
frame.setSize(500, 400);
frame.setTitle("Properties of " + nume);
ok = new JButton("OK");
no = new JButton("Cancel");
modified = true;
// <"Labels, sliders ,text fields"> // <“标签,滑块,文本字段”>
// <"add the components on the panel"> // <“在面板上添加组件”>
buttonsPanel.add(ok);
buttonsPanel.add(no);
JSplitPane framePanel = new JSplitPane(JSplitPane.VERTICAL_SPLIT, jsp, buttonsPanel);
framePanel.setDividerLocation(0.9);
framePanel.setDividerSize(0);
framePanel.setResizeWeight(1);
frame.add(framePanel);
Here is what my frame shows the 1st time: 这是我的框架第一次显示的内容:
And then after I resize it the values appear: 然后,我调整其大小后,将显示值:
