Java Parent and Child JFrame
提问by Jin Ginusuke
I'm new to javax.swing.*packages and only familiar to c#.net.
I have two JFrames namely frmLoginand frmMainrespectively.
All I want to do is a simple code something like this:
我是javax.swing.*包的新手，只熟悉 c#.net。我有即两个JFramesfrmLogin和frmMain分别。我想要做的只是一个简单的代码，如下所示：
+----- C# version ---------
+----- C# 版本---------
this.hide();
new frmMain().ShowDialog();
this.show();
tbPsswrd.Text = String.empty;
+---- JAVA version -------
+---- JAVA 版 -------
this.setVisible(false);
new frmMain().setVisible(true);
this.setVisible(true);
tbPsswrd.Text = "";
+---------------------------
+----------------------------
In Java JFrame, only show()and setVisible(boolean isVisible)is available,
hence even though I'm not finished with frmMain(), it will continue to do the
rest of the code next to it (which is to show the parent form and empty the password
box).
在 Java JFrame 中，只有show()和setVisible(boolean isVisible)可用，因此即使我没有完成frmMain()，它也会继续执行旁边的其余代码（即显示父表单并清空密码框）。
In summary, I want an equivalent functionality of method .showDialog();not just .show();so that it wont continue to the next codes unless I closed the child form.
总而言之，我想要一个等效的方法功能，.showDialog();不仅.show();如此，除非我关闭子窗体，否则它不会继续执行下一个代码。
Thanks in advance! ü

Use a modal JDialoginstead of a JFrameand dialog.setVisible(true)will block until the dialog is closed. For example:
使用 modalJDialog而不是 aJFrame并且dialog.setVisible(true)会阻塞直到对话框关闭。例如：
JDialog dialog = new JDialog(parentFrame, true); // parent, isModal
dialog.setVisible(true); // blocks until dialog is closed
// ... do stuff after dialog is closed
