Advice needed

Postby PeterHarmes » Tue Jun 23, 2009 1:28 pm

Hi,

I'm trying to create a MDI window, that can open multiple MDI Child windows that each browse the same database (each window opens a new instance of the database and gives it a unique alias) I have tried to create my own class, and i call a :new() to open the windows/databases/browse etc.

I am now adding a menu to the MDI window, but have the problem of knowing what window is highlighted and to which object the window refers to.

My class stores the alias name of the browse and i was hoping to reference this in the action of the menu (oObject:cAlias->TICKET_NBR) but i don't know how to reference the Object that is selected.

Any help will be appreciated

oWnd:getActive() returns the active MDI child window (where oWnd is the main window).

If you use database objects then you don't need to deal with aliases.

I've solved my problem - i just pass Self to the menu function and i can then reference the aliases of the databases used. It was pretty obvious really, it's amazing what happens after you've had some sleep!!!

Another question,

When a child closes, i would like the wondow to automatically retile the remaining child windows. I've tried to call :tile(.T.) on the valid of the child window, but i think that the app thinks the window is still open. Does anyone know how i can achieve this?

Regards,

Pete

>I've tried to call :tile(.T.) on the valid of the child window, but i think that the app thinks the window is still open.

When the valid is called, the window IS still open--the window only closes after the valid is executed.

You can try using a timer in the valid so it tiles after the window is closed.

These issues are why I never use MDI windows. There is way too much effort for the user spent manipulating windows. A SDI interface like Outlook is much easier for the user.

Next question...

If I have 3 tiled MDICHILD windows opened and i want to resort the order that they appear by dragging the bottom window above the second window, is there a way to call a tile when the mouse button is released? I've tried the bMoved option but, this is called as soon as the window is moved not when the mouse button is released.

Any ideas?

Thanks
