Crystal Toolkit is a Windows Forms (.NET Framework 2.0) control library written in C#. This is the eighth release and contains the following updates:
New features.
-
CrystalPictureShowController: Allows you to tie the common elements of an image viewing application in one controller. Create a form with CrystalImageGridView, CrystalPictureShow, a combo box and trackbar for image scaling, toolbar buttons for navigation. Set all these elements in the controller and you are off and running. You still need to handle the split container and certain events (like initiating and terminating full screen modes) but the sample program below will show you how to do that.
CrystalComicShowController: Allows you to tie the common elements of a comic book viewing (reading CBZ or CBR archive files) application in one controller. This may be the first C# toolkit designed to allow you to read CDisplay compatible files. Create a form with CrystalImageGridView, CrystalComicShow, a combo box and trackbar for image scaling, toolbar buttons for navigation. Set all these elements in the controller and you are off and running. The internal framework uses CrystalMemoryZipCollector for CBZ files and CrystalRarCollector for CBR files.
Enhancements.
-
CrystalCollector: Virtual methods moved from CrystalFileCollector to the base class. Sorting methods, Copy, Move, Delete, Rename, Select operations are moved here so that all derived classes can use them.
CrystalImageGridView: FocusedImage property added - returns the current focused image. CenterCrystalImage public method added - centers the given image in the grid.
Demo Programs Expanded.
-
CrystalPictureShowController Demo: shows how to use the new controller to quickly develop an image grid viewer. This sample also shows you how to put the main form into a menuless, toolbarless, fully zoomed mode that takes over the entire screen. Just click on the Full Screen button. The Slideshow mode has been expanded to include an options dialog to allow you to set certain options like Shuffle, Repeat, or SlideShow effect.
-
CrystalComicShowController Demo: shows how to use the new controller, and in an indirect way, how to use CrystalToolkit to pull images out of compressed files. To get the full benefit of this demo, you will need to have a CBR or CBZ file on your hard drive. Run the demo program, click File\Open Comic Archive and open up the CDisplay compatible file. You should see the thumbnails start to appear and then the app zooms into full screen mode. Press ESC and you will see the sheet of thumbnails representing the comic book pages.
Bug fixes.
-
CrystalImageGridView: Right-mouse button no longer clears item selection.
This release comes in a ZIP file. Simply unzip the contents to your hard drive, navigate to the root Attilan folder, and double click on CrystalDemo.sln. This solution file contains the Crystal Toolkit plus demo programs. Just build the solution (which compiles the CrystalToolkit library first) and run the demo programs to see how they work. You can run the demo programs without building the source by clicking on "StartDemo.bat" in the root Attilan folder or CrystalDemoLauncher.exe in Attilan\bin.
I've tested the demos under Windows XP SP2 and Windows Vista. Needless to say, buyers beware, this is alpha software and it's free open-source code: you get what you pay for! I'd welcome any feedback, bugs (or bug fixes), and thumb-bitmap replacements. Send email to richard [at] attilan {dot} com.
