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.

Matze5590

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;
}
@

Matze5590

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:
.
.
.
};@

Matze5590

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?

Matze5590

i tried it with .jpg files now, and it worked.
but it is very buggy now. so very often the wrong files are shown, or the files are not correctly positioned or both! maybe its a problem of icons?? i use these .jpg files as icons on buttons.
i will try to upload a small sample.

alexander

Not sure that is a problem of icons.
