How to get subwindow events in main window?

Hello,

I have application with some subwindows attached to main window.
Is it possible to get events and messages sent to subwindows on main window?
I mean is it possible to forward some events from child window to parent (similar to HTML DOM events bubbling)?

Actually I have Toolbox Treeview control in the subwindow and when I drag-and-drop file from Filer to the Treeview I not get DataLoad/DataSave messages. Drag-and-drop to main window work ok.

What language are you using for your development, and are you using any standard libraries to interface with the Toolbox?

Hello,
I have some experience with the Treeview module, I use it with !Diderot and I can drag and drop file from filer to load it.
With Toolbox ResEd for the treeview gadget you have to check “Deliver all wimp events”
Another interesting thing if you have several Treeview, you can get the handle of the window used to build the treeview, (thanks to Rick after asking him), which is not the case with the TextArea…
An example is my little application/demo XmlEdit
The ToolBox is the right way to develop with RiscOs, that’s my opinion..

I’m using C/C++ for development.

Thank you for info about “Deliver all wimp events” i will try it. Some problem that my TreeView is in the own subwindow, i mean my the chain is: TreeView→Subwindow→MainWindow.
I guess one way to handle all drag-drop events is listen an events for Treeview window handle, subwindow handle and for main window handle.

If I’m not mistaken, for the drag and drop of a file it’s a DataLoad message that the application receives.
The content of the message structure makes it possible to know the destination window.

Correct, in a Wimp application, dragging and drop of a file from a Filer window generates a DataLoad message, whereas drag and drop from another application’s save box generates a DataSave message.

I’ve never programmed with the Toolbox so I don’t know whether the events appear differently there.
