Hi all, I meet an problem about switch two Qt applications on my Embedded Linux soc.
I have written an application "Launcher", which will start other applications using QProcess. It calls hide() when the new app start, and calls show() when the new app is closed. This works normally. Now I want to the two applications can be alive at the same time. I tried to call hide() in the new app, and then send messages(D-Bus) to Launcher. When Launcher receives this message, it will call show(). But Launcher didn't show again, and the screen is black. After debugging, Launcher did receive the message and show() is called. I don't know why it doesn't display again. This method works normally on Ubuntu pc. I want to know if Qt embedded supports this feature or not? My Qt version is 5.0.2. One work round is to write one application to do all work, but it seems too complicated. Does anyone have met the same issue before? What is your solution for application management? Is one application the general solution for this? Best regards, Xubao
