[Qt-interest] QProcess and Qt/Embedded.

[simith nambiar]

Hello All,
            I have been searching the Internet for quite sometime, but i haven't found a perfect solution, maybe there isn't one or i have missed something.

I need to develop a set of applications for an embedded platform (screen size around 800 X 600 pixels ), currently i have installed Qt/Embedded (4.5.1), Qt/X11 ( 4.5.1) , both work fine on my desktopp. I use the Qvfb program and it looks good.

The Fluidlauncher demo, which launches each demo is excellent to understand the way to use the QProcess to execute other Qt programs.

I need to write a similar Application where i can launch applications from a Fluidlauncher like interface. The only thing i'am missing is the way i can keep the process running in the background and switch views between these multiple applications. I do not want to start the QProcess each time the user clicks on the Application icon.

For example, when the user selects Application 1, and then exits it, i need a way to keep the Process alive, but give control back to the Launcher. The User then enters Application 2, and so on. On each exit from the application, i only want to save and resume state.


Basically i need a framework for maintaing the state of each application without exiting it , when i enter the next application. I want the framework to be small in size,

Please suggest whether i should write one on my own, in that case any pointers would be helpful, else if one exists please send me some pointers.

Thank you.

Cheers,
Simith Nambiar
