Change text of JTextField from different Class
How can i change the text of a jTextField from other class
Suppose i have Class A in which if i select an item and click create account. I added a tab with same name to my jTabbedPane. This tab is class B. the code for this is:
onclick on "Create Account" this function addclass(mainCB.getSelectedIndex()) has been called
public void addclass(int a) {
String s=(String) mainCB.getItemAt(a); //mainCB is variable name of combobox
JComponent subpanel2=new B(); //added the class
jTabbedPane1.add(s,subpanel2); //added new tab which is the new class
B ob=new B(); //object of new class B
ob.heading(s); //heading is the function in Class B
}
Now how can i Change the jTextField1 text from class A.
heading() function in class B is as follows:
public void heading(String s){
head.setText(s); //head is the variable name of jText开发者_Python百科Field1 of class B
}
I have posted the image of both the classes A and B.
This is Class A
The new panel which is added in jTabbedPane is class B. This is being called in class A.
You create two instances of the class B
in your addClass
method. I think it would solve your problem to call heading
on subpanel2
, which is of type B
. This would go something like:
public void addclass(int a) {
String s=(String) mainCB.getItemAt(a); //mainCB is variable name of combobox
B subpanel2=new B(); //added the class
jTabbedPane1.add(s,subpanel2); //added new tab which is the new class
subpanel2.heading(s); //heading is the function in Class B
}
Is this what you wanted?
