Last week Xojo 2017 Release 2 hit the download servers. This release has the usual mix of new, changes, and bug fixes. At first blush it doesn’t seem like there is a lot to mention but there is, but I’ll get to that in a minute.
Before we get into the highlights it’s worth mentioning, again, that R2 does not have 64-bit debugging for Windows. As Xojo mentioned in their blog post (http://blog.xojo.com/2017/07/26/the-best-laid-plans-64-windows-debugging/) the LLVM compiler and toolset just wasn’t ready to be included in R2.
Despite the lack of a 64-bit debugger for Windows a number of things were corrected in 64-bit Windows builds. Icons are now applied correctly and they also show the correct version information. The 64-bit MS SQL Server database plugin now works when compiled on the Mac. Game Input Manager also works in 64-bit now. Images assigned to an ImageWell are now drawn properly.
Also related to 64-bit builds, the Split and Join functions for Unicode strings is much faster and Replace and ReplaceAll behaves like the 32-bit versions. Exceptions no longer leak memory. Virtual Volumes now work. Copying a picture to the clipboard now works. XojoScript is now available in 64-bit builds.
Linux GTK3. See Xojo blog post (http://blog.xojo.com/2017/08/15/goodbye-gtk-2-hello-gtk-3/) detailing some of the changes. The switch to GTK3 was necessary for HiDPI support and now scales automatically on integral scale factors (i.e. 1x, 2x, 3x, etc). This also lets child controls clip properly on parent controls whereas they did not always clip properly in prior versions.
Be aware, though, that this switch may affect how your controls draw. While it’s always been true that default control sizes are bigger in Linux you could sometimes cheat and use the open events (or subclass the controls) and make them slightly larger in Linux and perhaps make the system font a little smaller and things would look good enough to not require a bigger UI change. With this switch to GTK3, however, it seems like some controls, PopupMenu and Pushbutton come readily to mind, in that their caption location is definitely lower than the prior version thus making them look odd without more work. For me, what worked in R1.1 just doesn’t look good in R2.
This change begs the question that if we could make a Xojo theme for Linux that would make control heights smaller, text sizes smaller, and change the caption locations to make this a non-issue. Perhaps someone with more knowledge about Linux themes could answer that.
A few other things that might ruin your day in Linux is that not all Linux distributions now allow you to remove the border of TextFields. It wouldn’t surprise me if additional issues are found in GTK3 as time goes on.
iOS has a couple of important changes. The first is that the AutoLayout Priority property in prior versions was calculated on its own. In R2 new constraints get the ‘Required’ priority. Any existing projects should get thoroughly tested on multiple sized devices to make sure nothing needs to be fixed. In our own testing we had to simply change the priority to Required to fix any issues.
Another iOS change that may affect you is that setting the CopyFileStep to the “Frameworks” destination now properly creates the Frameworks folder inside the iOS package and puts the files there. Before you had to create a manual directory for it to work properly.
Another nice fix is that a numeric suffix is no longer added to copied iOS controls unless they need it. This was an annoying bug. Not hard to fix but annoying nonetheless.
The Session timeout now takes touch events into account when figuring out the last interaction with the app. In addition to that, web apps now try to reconnect if they’ve lost connection to the web app and will continue to do so for three minutes or until the user navigates away from the disconnect screen.
The Listbox control received some updates. For Linux, HelpTags are now positioned properly and in Windows they disappear properly when the mouse leaves the control Also in Windows the endcap is drawn correctly and headers no longer flicker when hovered over by the mouse or when clicked on.
A regression was reported for R2 that affects dragging items to the Listbox. In Windows the X & Y coordinates are incorrect. This was reported in Feedback 49190.
New Drag events were added to the Listbox. Except for a jumbled paragraph in the release notes I’m not sure anyone would notice. I would spend more time talking about it but as far as I can tell these are not documented in the Language Reference, either local or online and there is no example. I find it inexcusable to have a major change to such an important control not be documented. This seems like it should automatically make it into the documentation. Do better Xojo!
The IDE received a bunch of bug fixes and changes. New items in the Menu Editor no longer ‘fly in’ and arrow keys work now. Long error messages are wrapped and row heights adjusted in the error reporter are adjusted as needed (as a side note does this forebode variable height list boxes?) Recent Items in the Project Chooser now show size, date created, and date modified when possible. Pressing the Escape key now acts as a “Revert Now” to changes.
It also appears that a regression bug was introduced in Raspberry Pi. Button.Action events don’t fire if using a touchscreen. They appear to work properly when using a mouse. Feedback 49221.
As always, look through the release notes to see what else has changed. It’s also a good idea to test your applications thoroughly when upgrading to a new version.
Xojo 2017 Release 2 was chock full of new things and changes. I hope a dot release is issued to fix some of the bigger regressions. Up next is 64-bit debugging and remote debugging, the new plugin format, interops, and Android. Think they can get it all done in 2017?
Sorry for the delay in getting this out. Those pesky clients sometimes want on-site help and the last thing I feel like doing is writing after a long day of coding.
