Nokia N8 showFullScreen() don't work

Matze5590

Hi,
i can't use showFullScreen(); with my Nokia N8.
The App exits at the beginning.
But when i rotate my phone and try it once more, the App is shown.
How can i solve that?

Thanks!

At this example too?

@ int main(int argc, char *argv[])
{
QApplication a(argc, argv);
QDialog dlg;
dlg.showFullScreen();
return a.exec();
}@

error:
aggregate 'QDialog dlg' has incomplete type and cannot be defined
?

edit: i forgot to include

Matze5590

okay, it works, but how can i get my buttons into the dialog now?

edit: now there is just a gray screen

alexander

Just add your button to the dialog.

how can i show the mainwindow.ui??

alexander

Write your own class from QDialog.

@#include <QDialog>

namespace Ui {
class TestDialog;
}

class TestDialog : public QDialog
{
Q_OBJECT

public:
explicit TestDialog(QWidget *parent = 0);
~TestDialog();

private:
Ui::TestDialog *ui;
};@

@TestDialog::TestDialog(QWidget *parent) :
QDialog(parent),
ui(new Ui::TestDialog)
{
ui->setupUi(this);
}

TestDialog::~TestDialog()
{
delete ui;
}
@

okay, i canged 'QMainWindow' to 'QDialog'. everything semms to be allright,
but i still just get the gray screen. the setupui looks great so i have no idea whats wrong.

alexander

show your code

Matze5590

main.cpp:
@int main(int argc, char *argv[])
{
QApplication a(argc, argv);
QDialog dlg;
/MainWindow w;/
dlg.showFullScreen();
return a.exec();
}
@

mainwindow.cpp:
@#include "QDialog"
MainWindow::MainWindow(QWidget *parent) :
QDialog(parent),
ui(new Ui::MainWindow)
{
ui->setupUi(this);

}

MainWindow::~MainWindow()
{
delete ui;

}@

mainwindow.h:
@#include <QDialog>

namespace Ui {
class MainWindow;
}

class MainWindow : public QDialog
{
Q_OBJECT

public:
explicit MainWindow(QWidget *parent = 0);
~MainWindow();

private:
Ui::MainWindow *ui;

private slots:
.
.
.
};@

and mainwindow.ui:

@<?xml version="1.0" encoding="UTF-8"?>
<ui version="4.0">
<class>MainWindow</class>
<widget class="QDialog" name="MainWindow">
<property name="windowModality">
<enum>Qt::NonModal</enum>
</property>
...@

Well, based in the code you posted, you don't instantiate-and-show your MainWindow in main.cpp, just a standard QDialog :-)

alexander

why QDialog, must be MainWindow:

main.cpp:

@int main(int argc, char *argv[])
{
QApplication a(argc, argv);
MainWindow dlg;
dlg.showFullScreen();
return a.exec();
}@

okay, thanks!
but now i have the same problem again:
i can only start the app when i rotate the device!
its not possible to run it while the device is in the normal position!
the app is exiting always!

alexander

comment this line
@ui->setupUi(this);@
does program work?

Matze5590

no, even not when i rotate it!

alexander

But with QDialog all works correctly?

Matze5590

no, it crashes when i start it. its just working with the gray screen when i dont add buttons etc..
there has to be a problem with showFullscreen() because when i use showMaximized everythings ok, but than theres to low space for my app.
any idea?

Matze5590

ok, i tried around an found out that its not a problem with showFullscreen();.
Its seems to be a problem with the images i have used.
i removed all my .bmp files and the app works.
now i dont use images, but it looks bad, so what can i use therefor now?
or is it maybe a problem in the .pro file?
the line RESOURCES: images.qrc ?? but it worked fine with symbian 5th.
any other idea? or other image types to use?
thanks!

alexander

Can you write test with images? And upload it?
