Window is not in focus when opened

gabor53

Hi,
I'm opening a window widget from code. When that happens I already have 2 dialogs open.

QHBoxLayout *rev_Title = new QHBoxLayout;

    QFont f( "Arial", 18, QFont::Bold);
	revTitle->setFont (f);
    revTitle->setText ("Review the Data You Entered");
    rev_Title->addWidget (revTitle,Qt::AlignCenter);

    review_Window->setWindowTitle ("Review");
    rev_Layout->addLayout (rev_Title);

    review_Window->isModal ();
    
    review_Window->show ();
    
    review_Window->setFocus ();

Everything works nicely, but the new window is hidden between the 2 previously opened windows so it is not in the foreground. How can I open it in a way that it stays in the foreground and has the focus on it?

Thank you.

hi
you can try to call
http://doc.qt.io/qt-5/qwidget.html#raise
on it.

If you mean stay on top at ALL times then
there is a flag for that
Qt::WindowStaysOnTopHint
you can use with setWindowFlags
-BUT- it makes windows stay above all others all the time.
Not sure you want that.

Thank you.
I made the following changes:

    setWindowFlags (Qt::Popup);
    review_Window->setWindowTitle ("Review");

The new window does stay on top. I have 3 dialogs open:
mainwindow
additem
review_Window

Review_window is generated by additem. When review_window opens (and stays on top) it closes additem which I still need open. How can I keep additem open?
Thank you.

Hi you must show the code for how you open
additem and review_Window
as there is no reason for review_window to close additem so I assume
its something with your code. Like using exec instead of show or
using a local variable for additem so it runs out of scope and be deleted.

@mrjj
Here is the code opening additem:

    Additem mAddItem;
    mAddItem.setModal (true);
    mAddItem.exec ();

and this opens review_Window:

    review_Window->isModal ();

    review_Window->show ();

    review_Window->setFocus ();

Thank you for your help.

Hi
Additem mAddItem;
is local variable it seems but you are using exec() should should not run out of scope.
Please put a break point on next line after
mAddItem.exec ();

and see if it for some reason falls out of exec() when u open review_Window.

Do you use a slot/button to call the code that opens review_Window?

@mrjj
Hi,

    Additem mAddItem;
    mAddItem.setModal (true);
    mAddItem.exec ();
    break;

generated an error message: break statement is not within a loop or switch.

Yes, the review_Window is opened in a function triggered by a slot/button.

Thank you.

hi
i imagined something like
mdditem mAddItem;
mAddItem.setModal (true);
mAddItem.exec ();
int a=100; <<< break point here.

@mrjj
Hi
I tried.

    Additem mAddItem;
    mAddItem.setModal (true);
    mAddItem.exec ();
    int a = 100;

Nothing really happened except I got a message saying unused variable.

@gabor53
hi
did it stop at break point when review_window open?
meaning it went from
mAddItem.exec (); << should stay here
int a = 100; << should not go to this line when review_window

also
review_Window->show ();

this is how u open review_Window still ?

Else Im afraid I cant guess what you are doing wrong.
Normally its not an isses to have 2 dialogs so must be some small details.
So u are almost there:)

Hi
It did not stop at breakpoint.
I open review_Window like this:

    review_Window->setFocus ();
    review_Window->show ();

New development:
I haven't changed anything. Now all 3 windows (mainwindow, additem, review_Window) stay open. They are stacked from top to bottom like this: additem, review_Window, mainwindow. The minimize button doesn't work when all 3 windows open. If I close one of them everything works. No idea why. Thank you for your help.

mrjj

Hi
When you call exec on a dialog, it become modal.
This means that other windows are blocked. also including minimize button.

That might be the reason.

@mrjj
Thank you. I redid the code and it works now.
