Calendar Combo Pop-Up Displays on Primary Monitor Regardless of Application Window Position

[ShahzaibIbrahim]

In the CalendarCombo widget, when connected to a dual-monitor setup with the secondary monitor on the left and the primary monitor on the right, selecting the calendar combo causes the pop-up to always appear at the (0, heightDoesntMatter) coordinate on the primary monitor (the far left). This behavior is due to a specific condition implemented within the code, resulting in the pop-up consistently displaying on the primary monitor rather than aligning with the application window's actual location.

This blocks us to use this widget in multi-monitor environment.

HOW TO TEST

• Change the zoom level of your monitor to any zoom above 100 in display setting
• Run the ExampleApplication.java
• Go to CalendarCombo Tab
• Move the window to secondary monitor (on the left)
• Click on the combo
