142 EZwarePlus Programming Manual
When the HMI initializes, it displays the startup screen (Window #10) and the default common window.
To change common windows, we press the CCW function key that has been configured to change the common
window to Window #30.
Window #30 remains the common window until another function key object is pressed that changes the common
window or until the HMI is reset.
Using the Fast Selection Window
In the last section, you read that common windows are great for displaying information that should be displayed all
the time, regardless of which base windows are active. You may also create projects that require a window that is
always accessible (like a common window) but not always displayed. For example, you may want a numeric keypad
available for any data entry; however, a keypad takes precious space on the HMI display. Ideally it should appear on
screen only when a key was pressed and then, by pressing another (or the same) key, the keypad should disappear.
This is essentially the purpose of the Fast Selection window. The Fast Selection window can also be used as a menu
key that allows the HMI operator to rapidly switch screens.
Whenever a new project is created, the fast selection window (Window #3) is automatically created (except when
Portrait mode is selected; you can create a Fast Selection window using the Window > Open Window > New… > Fast
Selection command).
