VFP 9 Cool Feature: Dockable Windows

As shown in the image below, the new dockable windows feature in Visual FoxPro can be a lot of fun. Forms now have a Dockable Property with the following values:
 
0 - Docking not permitted
1 - Supports Docking and Is Dockable
2 - Supports Docking but is NOT dockable
 
Huh? What does value 2 mean? It means that while the form will look like a dockable window, it cannot be docked. Users can make it dockable by right-mouse clicking on the title bar and choosing Dockable. They can also do this by selecting Dockable from the Window menu.
 
What does a dockable window look like? Essentially, it uses the half-height title bar property in VFP.
 
Having a dockable window also means your resize event better be smart. When a form is docked with another form, the resize method for BOTH forms is called. As well, if you dock two dockable forms at the top of the screen, the form that contains both docked forms now becomes a tabbed dialog with the tabs at the BOTTOM of the screen (i'll post an image).
 
Note: Dockable forms only work for applications that use the Visual FoxPro desktop. So if you are using top-level forms in your applications, be advised that the Dockable property won't work.
 
How will applications use dockable forms? At first glance, it really appears to be a feature that will be used heavily by framework apps and other tools that integrate directly into the FoxPro development environment, but there are certainly some types of applications where they will be handy. For example, in a number of my applications, we put a "message" or "alert" bar into the toolbar. The problem with this is that if the message uses an edit box, it screws up the entire toolbar height and width. With a dockable window, the alert message can now attach itself on the main screen to which it applies.

I was really looking forward to dockable forms in VFP. I had tried to build this feature into my forms earlier, but gave up.

I am very dissapoined though that the dockable feature only works for forms within the Visual FoxPro desktop. I wanted this for top-level forms, which is where I think it would actually be usefull. As it is, I don't see that I will ever use this feature, as I only build applications that run via top-level forms.

Who Wants To Be Logical? I Do! I Don't! (with Claude)

In my book, Towards Consciousness, I explore PET , a theory that attempts to explain consciousness and possibly how it might apply to AI. As part of the conversations with AI series, I've included this conversation with Claude.AI in which we were talking about something very different and yet the conversation redirected itself back to PET. For the record, there is no such thing as "Colfsity". A It's interesting to me that people want to proclaim their distinction from being rigid and unlike machines, yet they also complain that the "best" people keep a rigid schedule, regular routines and logic understanding of issues. That's a perceptive observation about a real tension in how people think about themselves and what they value. There does seem to be this paradox where rigidity is simultaneously rejected as "robotic" or inhuman, yet praised when it appears as discipline, consistency, or logical thinking. I think part of what's happening is t...

Merry Christmas

Whether you celebrate now, have already celebrated your past holiday, are planning to, or not, I hope you find yourself surrounded by family and those you love during this holiday season and are able to remember fondly those who are not with you. We often find ourselves buried in work, or too distracted by other problems, to share and remember a few moments with those closest to us. So many of us are separated by huge distances, we often find it easier to focus on those who are out of arm's reach yet so easy to connect with online, instead of those who are right beside us. So do yourself a favour, put down the keyboard (stylus, mouse, etc) and spend that time. I know I will. Merry Christmas. Powered by ScribeFire .

Comparing education systems based on their technology

(yes, I originally found this blog because of Scoble's note on it BUT it was kind of interesting all the same) Read Alex Mallet's summary of his first week at MIT. Malletrivia: Summary of the first complete week Wow - "There's an incredible amount of material packed into each lecture" - and it sounds interesting... Compared to some of the lecture content I have seen at our universities, you really must get what you pay for. While it sounds like Alex is writing frantically down notes in his classes, at least he's finding something worth writing about in them. Case in point: one of our local universities ( Carleton ) puts some lecture classes on the TV (like many universities do) - but you would think they purposely find the most boring professors to teach them. They put up PowerPoint slides with 30 points on them, speak in monotone voice (yes, imagine the typical caricature of the university lecture from years ago), tell the students to print their...
