desktop vs embbeded when using Qt virtual keyboard

[Circuits]

I was reading the basic example for the Qt virtual keyboard it shows the following snipit when describing how the application chooses to use the embedded version or the desktop version:

disable-desktop|android-embedded|!isEmpty(CROSS_COMPILE)|qnx {
    DEFINES += MAIN_QML=\\\"basic-b2qt.qml\\\"
} else {
    DEFINES += MAIN_QML=\\\"Basic.qml\\\"
}

could some explain what's happening in this line:

disable-desktop|android-embedded|!isEmpty(CROSS_COMPILE)|qnx {

is this some kind of if/else statement? If so, what exactly is the condition?

Yes. qmake syntax is described in detail here: https://doc.qt.io/qt-5/qmake-language.html#scopes-and-conditions

| means OR in qmake, ! is a negation. So this condition reads:

disable-desktop or android-embedded or (is not empty(CROSS_COMPILE)) or qnx

and that branch will be executed is any of the conditions are true (that is: if CONFIG value contains them).

Hi,

Yes it is. See the scope syntax part for the qmake language chapter in Qt's documentation.

@sierdzio So, what if I were to use the Basic.qml (desktop version) with an embedded application? Wouldn't it just show the keyboard as a popup window? Or would it just not work at all?

I have no idea. I don't know what is in either of these files.

If your window manager supports multiple windows - yes it will likely be a popup. If it does not support multiple windows, it likely won't be a popup ;-)

Or would it just not work at all?
