[英]Controlling one JFrame from another jframe while opening third jframe in java
I have 3 different JFrames. 我有3个不同的JFrame。 One
Jframe
is a login page another has progressbar
and the third one is main page. 一个
Jframe
是登录页面,另一个具有progressbar
栏,第三个是主页。 Now what i want is that when we login in I want to show progressbar
above login page and on completing progress to 100% I want to close both frames and open third Jframe
which is main page. 现在我想要的是,当我们登录时,我想在登录页面上方显示
progressbar
,并在完成进度到100%时关闭两个框架并打开Jframe
主页的第三个Jframe
。 please kindly help me get this done. 请帮助我完成此任务。 Thanks //here is the code part.
谢谢//这里是代码部分。
rs=pstmt.executeQuery();
if(rs.next()){
progressbar prb=new progressbar(user);
prb.setVisible(true);
}// this open my 2nd JFrame of progress bar } //这将打开我的第二个JFrame进度栏
//next in Progressbar page i have this code // Progressbar页面中的下一个我有此代码
`public progressbar(String user) {
initComponents();
setLocationRelativeTo(null);
t = new Timer(35, (ActionEvent e) -> {
count++;
pb.setValue(count);
if(pb.getValue()<100){
pb.setValue(pb.getValue() + 1); // it makes bar progress
}
// after progress is 100%
if(pb.getValue()== 100){
t.stop();
this.dispose();
Mainpage mp=new Mainpage(user);
mp.setVisible(true); // this opens my Mainpage
}
});
t.start();
}
// Now what I want is after progress bar completes, I want to dispose both the login page and progress bar page opening Main page only //现在,我想要的是进度条完成后的内容,我想同时处理登录页面和进度条页面的打开。
For closing JFrames use command yourFrame.dispose();
要关闭JFrame,请使用命令
yourFrame.dispose();
Setting progressBar to 100% is easy via yourBar.setValue(yourBar.getMaximum());
通过
yourBar.setValue(yourBar.getMaximum());
可以很容易地将progressBar设置为100% yourBar.setValue(yourBar.getMaximum());
To hide/show components use name.setVisible(true);
要隐藏/显示组件,请使用
name.setVisible(true);
I won't use separate JFrame only for progress bar by the way. 顺便说一下,我不会仅将JFrame用于进度栏。
I can recommend you reading some doc about JFrame . 我建议您阅读一些有关JFrame的文档 。 If you want more specific answer, please post your code here.
