Best way to port from desktop targets

[lewind]

Hi,

I've read the port wiki but my app is already coded as Qt ui forms. What I'd like to have is the same graphical representations between Desktop (windows, linux) and mobile ones : Symbian (Meego if possible). What happen now, is that I have to rewrite the GUI part of my app as the layout doesn't seems to be adapted when I compile from Desktop->Symbian : edits, QPushbuttons are too smalls.

This lead me to create a separate project because the settings between targets are now differents.

• What is the best If I want to be platform independant ?
  

• do I have to rewrite the GUI in QML ?

If yes, my former choice for Qt was its nice C++ form, using java script would be a step back for me. In addition, then using Qt is less usefull knowing that if I have to use Javascript I could use other framework that have more mobiles range .

Hi,

It would be good if the GUI is in QML.

You can find instructions here

Also note that you can still use your C++ code for logic too. Using only javascript is not necessary.

thanks kusumk, I already knew that good Qt page.

My main concern is: does it worth the time to rewrite my app as QML graphics ?

I feel yes, since effort to implement UI in QML and integrating with C++ code would save time, as you need not worry of the application look and feel, for the phone, Depending on the platform for which the app is compiled, it provides very neat UI, takes care of orientations etc.
Otherwise you will have to struggle fixing these UI design issues for each platform and their versions.

totally right : that's currently what I have to face.

Teemup: do you have examples of implementing QML with logic in C++ please ?

The last slide from this link is about QML with C++

actually, you have no choice. till Qt5 there is only one way to create more or less up-to-date UI - QML plus qt components
when Qt5 will arrive, there will not be support for Symbian/Meego, so....stuck with Qt4.x/QtQuick 1.x etc...

Indeed that what I needed to know.

Thank you all for these precious information.
