Title: MDI Container: putting a focus on a specific "child" application Post by: S. on September 19, 2012, 04:55:37 pm I am trying to find a way to automatically set the focus to a specific "child" application, where a MDI container can have many different child applications.
So instead of opening just another application A, I want to put the focus on A if it is already open. If this is possible .. can somebody guide me or give me a hint ? best regards, Örn Sigurðsson Title: Re: MDI Container: putting a focus on a specific "child" application Post by: Lionel F. on September 20, 2012, 11:58:35 am Hello Örn,
This is something that has already been requested but that is not implemented yet. It corresponds to reference # 22263 of our issue tracker (MDI: Would like to have a new method: ui.Interface.showChild(appname)). I'll add you to requesters. Indeed the idea would be to put the focus on the already existing instance instead of starting each time a new one.

Meanwhile I will just prompt users to use [Ctrl] + [Tab] to move between applications, if they by accident try to initiate another instance of an application that is already open. cheers, Örn Title: Re: MDI Container: putting a focus on a specific "child" application Post by: Reuben B. on September 20, 2012, 11:18:36 pm Orn,
I'll just check, you are aware of CALL ui.Interface.getChildInstances(childname) https://4js.com/online_documentation/fjs-fgl-manual-html/User/ClassInterface.html#METHODS (second from bottom). The demo MDI example FGLDIR/demo/Containers/Main1.4gl uses it. So instead of "opening just another Application A" you can prevent another instance of application A opening. The other thing you might want to look at, I experimented with it at my previous employment before I joined FourJs AP, so I don't have the source, it might not work with MDI windows and it might not be appropriate for Windows Vista and 7. Look up AppActivate and VBScript. The concept being create a little VB script that is something like ... Set WshShell = CreateObject("WScript.Shell") WshShell.AppActivate "Title of your Child Window" ... send it to the client via FGL_PUTFILE() and then execute it via shellexec. Also a similar technique may require using the Windows Windows Id. The frontcall getwindowid can be used to get that and then passed into a similar script Hope that helps, Reuben |
