如何在新打开的jframe上关闭以前的jframe

Question

I have a problem in disposing the two JFrames in one click of a button. I have a 2 JFrames(SUC_Forms and add_suc) when the button "ADD RECORDS" in SUC_Forms was click another new JFrame will show which is the add_suc jframe that contains textboxes for registration/filing. When i press ok to validate and insert all the data in the database, a JDialogbox will pop-up for a confirmation. Once I hit "Ok" both JFrames will dispose and then SUC_Forms-JFrame will show again containing the updated data. I have a trouble on how the current JFrames has an access to the previous and active JFrame. Can you pls help me to solve this problem? Thanks in advance..

Heres my print screen.

SUC_Forms Code:

    add_suc add = new add_suc();
    add.show();

add_suc Code:

private void btn_okActionPerformed(java.awt.event.ActionEvent evt) {

    int verify = JOptionPane.showConfirmDialog(rootPane,"Are you sure you want to add this record?","", JOptionPane.YES_NO_OPTION);

    if(verify == 0)
    {

       String moa_id = txt_id.getText();
       Object region = cmb_region.getSelectedItem();
       String holder = txt_holder.getText();
       String brgy = txt_brgy.getText();
       String municipality = txt_municipality.getText();
       String province = txt_province.getText();
       String president = txt_president.getText();
       Object month = cmb_month.getSelectedItem();
       Object day = cmb_day.getSelectedItem();
       String year = txt_year.getText();
       String area = txt_area.getText();
       String allotment = txt_allotment.getText();
       String activities = txt_activities.getText();
       String status = txt_status.getText();
       String fill = "";

       if(moa_id.equals(fill))
       {
           JOptionPane.showMessageDialog(rootPane, "Please fill Moa ID!", "Message",JOptionPane.ERROR_MESSAGE,null);
       }

       if(region.equals(fill))
       {
           JOptionPane.showMessageDialog(rootPane, "Please select region!", "Message",JOptionPane.ERROR_MESSAGE,null);
       }
       else if(holder.equals(fill))
       {
           JOptionPane.showMessageDialog(rootPane, "Please fill holder!", "Message",JOptionPane.ERROR_MESSAGE,null);
       }
       else if(brgy.equals(fill))
       {
           JOptionPane.showMessageDialog(rootPane, "Please fill barangay!", "Message",JOptionPane.ERROR_MESSAGE,null);
       }
       else if(municipality.equals(fill))

       }

       else{

        try{

        st = con.createStatement();

        String query =  "insert into moa_suc values('"+moa_id+"','"+region+"','"+holder+"','"+brgy+"','"+municipality+"','"+province+"','"+president+"','"+month+"','"+day+"','"+year+"','"+area+"','"+allotment+"','"+activities+"','"+status+"')";

        st.executeUpdate(query);

        JOptionPane.showMessageDialog(rootPane, "Successfully added to the record!", "Message",JOptionPane.INFORMATION_MESSAGE,null);
        this.dispose();

    }
    catch(SQLException err){

        System.out.println(err.toString());

     }

    }
    else
    {
        JOptionPane.showMessageDialog(rootPane, "Sorry! No data added in the record!", "Message",JOptionPane.INFORMATION_MESSAGE,null);
    }

}

Answer 1

Since the JFrame you want to add the new record to is still open you could use a method in SUC_Forms where you pass the new record as a parameter. To be able to do that you would have to get a reference to SUC_Forms in add_suc. For example you can pass this reference to the constructor of add_suc when you are opening this Frame. Then you can call the method to add the record using the reference to SUC_Forms.

Your constructor would look something like this:

add_suc(SUC_Forms parent)
{}

And in SUC_Forms you create a method like:

public void addRecord(-here you pass the required parameters-)
{}

Your method call in add_suc would then be:

parent.addRecord(-parameters-);

I hope this helps you a bit.
