One of the integrated touch features of the VCL in RAD Studio 2010 is interactive multi-touch gestures. We call them InteractiveGestures because they fire the OnGesture event continuosly as the gesture is performed, allowing UI to be updated to reflect zooming, panning and rotation. InteractiveGestures are accessed from the new Touch property, as seen below:     There are 5 InteractiveGestures: zoom, pan, rotate, two finger tap and press and tap. Responding to an InteractiveGesture is as simple as adding an event handler for the OnGesture event.       The event handler is passed a TGestureEventInfo record which contains information about the gesture, such as location (point...

Finally! RAD Studio 2010 is just around the corner which means we can talk about all that new awesome "stuff" we've been working on. Chris Bensen and I have spent a lot of our time working on building a gesturing framework and integrating touch into the VCL. Here's a sneak peek of what's coming:   Most controls now have a Touch property, which hosts everything related to gesturing and touch.   The platform independant gesturing framework uses a mouse, pen or (single) touch and contains over 30 standard gestures (such as Left, Right, Up and Down). You can also record your own custom gestures using the Custom Gesture Designer.   There are 5 interactive multi-touch gestures (such as z...

TButtonedEdit preview
As I mentioned earlier I'll be posting a series of previews of new VCL features. First up is the all new TButtonedEdit component:                 Derived from TEdit, it provides embedded buttons that can optionally drop down a popupmenu (as seen above). We've used this new component in the Tiburón IDE, one example is shown here in a post by Chris Bensen.     ...

It's been awhile, more than awhile actually, but with Tiburón on the horizon, now's a great time to get some posts going! As I'm sure you know, Tiburón is all about Unicode support, but that's not all that's new in the VCL. I'll start posting some sneak peaks of the new VCL features shortly. In the mean time be sure to check out these Tiburón posts by fellow CodeGear bloggers: Tiburón - String Theory  Here Comes Tiburon Don’t Get Caught with Boxes Tiburon’s LoadFromFile and SaveToFile for Unicode characters    ...

After reading Chris Bensen's recent post about naming variables, I came across the following that made me smile:   FIsNotXP := not CheckWin32Version(5, 1); Later on FIsNotXP is used like this:   if (not FIsNotXP) and FInAnimation then ...
One of many new features in Delphi 2007 for Win32 is improved Vista support in VCL. New applications get these improvements by default, but what about existing applications? There are three easy steps you can take to make your application more Vista-like: Theme your applicationThis will change the appearance of most controls, rendering them using the currently selected Windows theme. From the Project menu, select Options, navigate to the Application page and check "Enable runtime themes". Use the MainFormOnTaskbar propertyWhen running under Vista's Aero theme you need to display the application's main form on the taskbar rather than the application window. This is required to correctly h...
It's taken a while, a long time in fact, but I'm finally ready to join the party, the blogging party that is. With the release of Delphi 2007 for Win32, I can't think of a better time to get this blog started. I work on the Delphi/BDS products, primarily on the VCL framework. Those who tried to watch my CodeRage presentation last week know that all too well. The pre-recorded presentation restarted after 4 minutes 20 seconds, then again after another 4:20, and so on until the presentation could be re-mastered. Just enough time for introductions and a teaser about what was to come. I guess it would be foolish to think Mr. Murphy would pass up an opportunity to particip...
