CCR.PrefsIniFile on GitHub

Just a small post to say the the native Preferences API wrappers for Android, iOS and OS X I published to Google Code a while back are now on GitHib:

Both the Android and Apple versions should also now compile in XE8.


Extended TClipboard implementation for FMX and VCL (CCR.Clipboard)

I’ve just pushed to GitHub (first time, so be gentle…) an extended, multi-platform TClipboard implementation for newer Delphi versions:

Where the platform allows, supports delayed rendering, virtual files, change notifications, and inter-process TClipboard-based drag and drop. The code originates from the FMX TClipboard I published a few years back, though is much extended, and was refactored to support the VCL too (XE2+). For more info, check out the readme first…

… followed by the wiki pages for discussion of individual features, together with known issues and limitations:

Disclaimer: supporting multiple FMX versions ain’t no fun, so if you come to try it in XE4 or whatever and have an issue, I may not be able to help you. Also, if you’re interested in drag and drop on OS X, consider using my code with any version lower than XE8 a ‘proof of concept’ only…


FMX TClipboard now supports iOS

I’ve just checked in a revision of my open source FMX TClipboard implementation that has an iOS backend. This supports the current rather than the FPC-based version of ‘Delphi for iOS’, however the Windows and OS X backends still compile with XE2 and above.

In essence, the new code wraps the native iOS clipboard API (UIPasteboard) and presents it in a fashion that closely follows the VCL clipboard interface, just like the existing Windows and OS X support did the same for desktop platforms. For some reason Apple in their wisdom decided to make the iOS clipboard API similar yet randomly different to the OS X one, so even though there’s not masses of code, it was a bit fiddly to implement. Anyhow, I’ve also knocked out a little demo similar to the previous desktop one:

TiOSClipboard demo

Using (say) Photos, you can copy an image to the clipboard and paste it into the demo. Conversely, you can from the demo itself copy either just the text entered, just the image, both the text and the image as two representations of the same clipboard item, or both the text and image as a custom clipboard format. The ‘List Formats on Clipboard’ button, as its name implies, then lists the formats currently on the clipboard. This is what I get after copying an image from Photos on the iOS simulator:

Format List

Technically, the iOS clipboard, like the OS X one, can have multiple items, each with multiple representations. Since the multiple-item concept doesn’t exist on Windows (indeed, it didn’t exist on OS X originally either), my class is only concerned with the first item, which is what most applications only bother with anyhow.

If you want the code, the SVN URL for it and a few other pieces is the following:

The core files are now CCR.FMXClipboard.pas, CCR.FMXClipboard.Apple.pasCCR.FMXClipboard.iOS.pas, CCR.FMXClipboard.Mac.pas and CCR.FMXClipboard.Win.pas, and together they stand alone.
