Both the JEDI Code Library and the JEDI Visual Component Library completed their move from Sourceforge to GitHub. The SubVersion repositories on Sourceforge are deleted/will be deleted soon. If you want to use the JCL and JVCL with RAD Studio XE4, you need to clone/download the JCL and JVCL from GitHub. There is no official… Read More: JCL and JVCL have completed the move to GitHub »

Here is a list of Mantis bugs reports for the JVCL that were fixed (by me) in the last 3 days. The number of open Mantis reports is now back at 2 pages. All the bug fixes are in the svn trunk head revision. Mantis #5017: TJvMaskEdit: Don’t validate on exit Mantis #5053: JvDBUltimGrid Search… Read More: JEDI Visual Component Library bug fixing session »

Yesterday our product manager came to me and asked me to replace our old splash screen with a new more fancy one that he had designed. The new splash image has alpha transparency and so we had to make our splash form a layered window. Unfortunately the UpdateLayeredWindow() API function doesn’t allow to use controls… Read More: JVCL TJvTransparentForm rewritten »

The JVCL package name change is now finished. All packages have new names following the name schema: JvXXXX.dpk for run-time packages and JvXXXXDesign.dpk for design-time packages. The BPLs have the $LIBSUFFIX C60, D60, 70, 90, 100, 110, 120 and 140 depending on the IDE version. And because installing the new JVCL head revision would leave… Read More: JVCL svn head is now working again »

The JVCL team just changed all their package names. This step was necessary because the current schema was Jv*D?R.bpl for runtime and Jv*D?D.bpl for designtime packages. So every packages had the Delphi version in its name. Nobody really knows why the JVCL didn’t use the $LIBSUFFIX compiler option that was introduced with Delphi 6, but… Read More: JVCL svn vs. git »

Once upon a time there was a nice and supportive DrawThemeTextEx function that was responsible for the country borders near the UxTheme.pas city. This function didn’t allow to communicate with citizens from the countries Windows 2000 and XP. A nice and smart guy who had to write a function that must communicate with countries introduced… Read More: Once upon a delayed JVCL time… »

The JEDI Project has released new versions of the JCL 2.0.1 (JEDI Code Library) and the JVCL 3.38 (JEDI Visual Component Library). Both include support for Delphi/C++Builder 6 to 2010. And because the trial version of RAD Studio 2010 doesn’t have a command line compiler which is required to install the JCL and JVCL, I have uploaded… Read More: JEDI Code Library 2.0.1 and JVCL 3.38 »

The JCL support for Delphi 2005 was broken for a long time due to a compiler bug. But today I figured out how to work around this compiler bug (I doubt that CodeGear will fix bugs in Delphi 2005). All Delphi 2005 users who couldn’t upgrade to a newer JCL can download the tomorrow’s daily… Read More: JCL and Delphi 2005 »

The JVCL has its own TJvGIFImage graphic class. In order to prevent conflicts with Delphi 2009’s TGIFImage class the TJvGIFImage isn’t registered for the *.gif file format. Unfortunately this makes it impossible for the IDE’s PictureEdit dialog to load a GIF file that can be used in TJvGIFAnimator. TJvGIFAnimator has a “property Image: TJvGIFImage” and… Read More: JvGIFAnimator/JvGIFImage and Delphi 2009 »
