focusing on a textfield in a panel which is in a tabbed pane that contains many panels

Question

I am working on a barcode application which has in its main GUI a tabbed pane that contains many panels where one of this panels is for the cashier, the problem is that when the cashier panel is displayed i need to always set focus on the textfield where the barcode must be inserted. requestFocusInWindow() or requestFocus() does not work since I am in the same jframe and in the same jTabbedPane but i am choosing panels inside this tabbedpane what i need is when i move to a specific panel which is "cashier panel" is always to set focus on a certain textfield thanks.

hmmm add `addChangeListener` to your tabbedpane .then when tab selected/change check if active panel is cashier.if panel is cachier then call `requestFocus()` — Madhawa Priyashantha, Sep 16 '15 at 08:06

private void MainTabbedPaneStateChanged(javax.swing.event.ChangeEvent evt) {

        if(CashierPanel.isShowing()){
            Barcode_txt.requestFocus();
        }       
    }

This may also work, when you specifying barcodeText's properties i.e. Height,Width etc set also focusable true as

barcodeText.setFocusable(true);
