Cannot Get Variable From Child Back To Parent In Java (options Window)

STARTED - 3:00PM UPDATE 1 - 5:36PM Apply Button in the Option() class: private void cmdApplyActionPerformed(java.awt.event.ActionEvent evt) {

Solution 1:

It's difficult to navigate through your very lengthy code sample, however take a look at your cmdApplyActionPerformed() method. You are creating a new HUD() and setting values in it... and then doing absolutely nothing with it.

If you are trying to use the "Apply" button to modify an existing HUD object, your class needs to have a reference to it somewhere. If the HUD is the parent class which creates the Options, try having the Options store a reference to the parent in its constructor. Then, when you perform changes like this in the Options, you can perform them on the parent rather than on a new variable which has no effect.

private HUD parent;

/**
 * Creates new form Profile
 */publicOptions(HUD parent){
    initComponents();
    this.parent = parent;
}

Then, in your event handler, you can have ...

parent.setTime(btnTxtTime);
parent.setTemp(btnTxtTemp);
parent.setSurface(btnTxtSurface);
parent.setWeather(btnTxtWeather);
parent.setRadiation(btnTxtRadiation);
dispose();

Solution 2:

From what I understand, HUD is your 'main window' and the users gets to this option frame from that window.

But when you apply, you're setting the properties on a new HUD, not the one you had before.

To fix this, you need a handle to your main window in your config window, so that you can set the properties on it.

in your hud:

ConfigFrameconfig=newConfigFrame();
config.setHUD(this);
config.setVisible(true);

In your config

privateHUD hud;

publicvoidsetHUD(HUD hud){
   this.hud = hud;
}

then just leave out the HUD hud = new hud();
