我创建了两个" jFrame表单"与netbeans。我可以同时打开这两个。此代码运行但没有效果。我尝试使用form1中的按钮setSelect form2中的复选框。不知何故,我无法影响另一个线程。你能帮我解决一下吗?谢谢。 (对不起,我的英语不好,我也在学英语)
这是form1.java(我删除了一些自动代码)
var typeCodes = ["061", "064", "065", "089", "090"];
$("fieldset[data-typecode]").filter(function() {
//Get fieldsets with typecodes in above array and with selected options
var code = $(this).data("typecode");
return typeCodes.indexOf(code) > -1 && $(this).find("select option:selected").length
}).each(function() {
//Do something on each fieldset
});
这是form2.java(我删除了一些自动代码)
package test;
import javax.swing.SwingUtilities;
public class form1 extends javax.swing.JFrame {
public form1() {
initComponents();
}
private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
new form2().setVisible(true);
}
private void jButton2ActionPerformed(java.awt.event.ActionEvent evt) {
final form2 click = new form2();
SwingUtilities.invokeLater(
new Runnable() {
public void run() {
click.jCheckBox1.setSelected(true);
}
}
);
}
public static void main(String args[]) {
java.awt.EventQueue.invokeLater(new Runnable() {
public void run() {
new form1().setVisible(true);
}
});
}
// Variables declaration - do not modify
private javax.swing.JButton jButton1;
private javax.swing.JButton jButton2;
// End of variables declaration
}
答案 0 :(得分:0)
在您的jButton2ActionPerformed
方法中,您正在创建一个永不显示的新JFrame。您不操纵jButton1ActionPerformed
中显示的JFrame。
试试这个:
package test;
import javax.swing.SwingUtilities;
public class form1 extends javax.swing.JFrame {
private form2 click = null; // this will hold the second JFrame (the one with the checkbox)
public form1() {
initComponents();
}
private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
if (click == null) { // only create the second JFrame once
click = new form2(); // this stores the second JFrame with the name "click"
click.setVisible(true);
}
}
private void jButton2ActionPerformed(java.awt.event.ActionEvent evt) {
SwingUtilities.invokeLater(
new Runnable() {
public void run() {
if (click != null) { // don't do anything if the second JFrame isn't displayed yet
click.jCheckBox1.setSelected(true);
}
}
}
);
}
public static void main(String args[]) {
java.awt.EventQueue.invokeLater(new Runnable() {
public void run() {
new form1().setVisible(true);
}
});
}
// Variables declaration - do not modify
private javax.swing.JButton jButton1;
private javax.swing.JButton jButton2;
// End of variables declaration
}
顺便说一下,这是一个糟糕的形式,并且对于以小写字母开头的类名来说非常混乱。将form1
重命名为Form1
,将form2
重命名为Form2
。
