Unsolved What is the differerece in MDI code?
-
Here is "main window" defined in MDI example
MainWindow::MainWindow()
: mdiArea(new QMdiArea)after mainWindow is defined in "main"
( Can somebody give non English speaking native VERBAL explanation of the above syntax? PLEASE )Here is same in QMDIAreaClass
QMainWindow *mainWindow = new QMainWindow; mainWindow->setCentralWidget(mdiArea);
It looks as a standard MDI example is not build using QMainWindow which would make better usage of Qt. .

Explanation: Main window constructor creates a new
QMdiArea
and assigns it tomdiArea
member variable.Btw. looks like call to parent class constructor is missing.
Here is same in QMDIAreaClass
QMainWindow *mainWindow = new QMainWindow; mainWindow->setCentralWidget(mdiArea);

I guess the purpose of MDI example is to show off QMdiArea and not QMainWindow, perhaps that's the reason. I have not looked at the code though.

Reason I asked - it looks as QMainWindow does what the MDI example - use "MDI area" directly - thus could be "bypassing " the application "standard" . Which seems more logical.
But you are correct - the examples are mostly for specific purpose and the "standard " application -> main window prevails in them. Nothing wrong with that.
I like the examples, but lack of comments and explanations why it is coded that particular way sure makes for more traffic here .
I am basically stuck trying to change the MDI "actions" example "default" sub-window to plain widget.

Oh yes, I fully agree.
