Hello,
I've recently discovered the usefulness of the MDI function in Developer. I'm currently working on a powerful application. There are a fair few MDI windows that load when the program starts and are always used, and I want to make it so that the user cannot close these. How can I do this? Also, is there a way to stop them from being resized or did I miss something?
That doesn't sound like MDI.
MDI windows are supposed to contain documents, your use sounds like toolboxes.
No, no. They contain frames. There are some that I don't want to be resized, e.g. the about box. I'm fully using MDI here. As for the other ones, they're key to how the program works, so I don't want the user to be able to close them.
You must be talking sub-applications because that's what it sounds like to me!
Yes, and the disable close option is disabled when you select MDI.
MDI frames should only contain user-created content, or pages of a help file or something like that. The about box is definitely an example of something that's not MDI. Anything key to using the program is also not MDI, eg toolboxes, menus, toolbars, pallets etc.Originally Posted by Shaun
A good example of MDI used to be MS word, but they abandoned MDI for an "each document in it's own copy of the program" approach, which is a lot nicer to use IMO.
Dynasoft, it's hard to explain. I'd have to show you the file to explain. Sadly I don't have it now. I was just saying that as an example. And I was talking about documents, yes. Forms. They're the ones that are using MDI! Why are we debating?I just want a solution.
Because we can't give you the answer to a problem that doesn't exist!
...It is a problem that does exist. I just want to know how to make it so MDI child window cannot be closed. There are some that I don't want to be closed as the frames the sub-apps are linked to are constantly handling data.
I just want to know how to stop them from being resized or closed. Yes, I can stop them being resized to a certain extent with Window Control, but that causes graphical errors usually; the frames go kind of black when it tries to resize the window back to its original size.
I have no idea why you other guys say that the problem doesn't exist.
Have a look at this screenshot and notice the left toolbox that can not be closed or resized. Okey, in the newer versions of Photoshop they are not true mdi windows, simply because you can move them outside the main window. But in the older versions of photoshop, that toolbox WAS in fact a true mdi child and could not be moved outside the parent window.
Having designed mdi applications in Visual Basic, I know that I was able to configure mdi childs to not be resizable or have a close button. I even clearly remembered that the setting was to be found at the same place as where you configured it to have a large (normal) or small (typical for toolbox) "drag" area. Will I have to create an example mdi application in Visual Basic just to prove it?
Unfortunately, I don't think MMF2 does it though.
