kandi X-RAY | tkx Summary
The Tkx module provides yet another Tk interface for Perl. Tk is a GUI toolkit tied to the Tcl language, and Tkx provides a bridge to Tcl that allows Tk based applications to be written in Perl. The main idea behind Tkx is that it is a very thin wrapper on top of Tcl, i.e. that what you get is exactly the behaviour you read about in the Tcl/Tk documentation with no surprises added by the Perl layer. In order to use Tkx, you need to understand enough Tcl to be able to read the documentation for Tcl/Tk and figure out how this maps to the Tkx. You will not need to write any Tcl code though, as all your GUI work, including the creation of megawidgets can be done in Perl using Tkx. The benefit of this approach compared Nick Ing-Simmons's classic Tk.pm module is that you can always use the latest features that Tk/Tcl provides and that you can use Tcl's native megawidgets directly. Tk.pm has stagnated recently because of the huge effort needed to port it to run with newer versions of Tk. The downside of the Tkx approach is that you will need to know a bit about Tcl and that you have to install Tcl/Tk on both your development and deployment systems. Another downside is that you will not be able to use any of the Tk:: add-ons or megawidgets already present on CPAN. Tkx is the toolkit used to implement the GUI frontends of ActiveState's PDK tools.

QUESTION
Using Perl v5.28, Tkx.pm v1.10 with ActiveState Tcl/TTk v8.6.9 ('aqua' style), on macOS v10.13.6. The demo below works as desired, enabling the calling of a given subroutine using either a GUI button push using the mouse, or using keyboard input with a 'normal' text character.
The one additional feature I would like to have is the visual feedback
of the graphical button being pressed (flashing) when the keyboard
alternative activation is used. I found what looks like a Tcl
solution using the event
generate command, and
a reference on using the Perl
Tkx::event_generate()
virtual event method call. I even found the equivalent Perl
Tkx::after(100) function call to create the suggested delay. But I
can't wrap my head around how to put this all together to achieve the
desired effect. Any help would be appreciated, with the understanding
that, like some other TTk features, this might not work on the Mac.

I have a program that will count the index length of a highlighted area. I wanted to use tix balloon to show the the result. But in order to use the tix balloon, it required me bind it to the a widget. Instead of binding it to a whole widget, I only want the balloon to show once when a certain event is being called.
Demo of my program (Count start and end index of the highlighted area)
Expected output The balloon will show the result beside the highlighted area

Creating your own tooltip is quite simpler than you think. This answer will give you an idea on how to make your own tooltip.
Create a show function that takes the indexes as parameters. Use .bbox(index) to get the position of the index and display the tooltip just above the selected letter.

QUESTION
Please help with any advice or troubleshooting tips for this error.
I'm in a small medical R&D+manufacturing company and we have a number of installations of Codesoft 2012, 2015, and 2018, on Windows 7 and Windows 10 machines. Codesoft is installed locally and each instance has it's own license, not running from a server. We have an in house application, developed by someone no longer here, (C# .NET VS2013) that we run which uses the Codesoft API for label printing. I made a few minor modifications to our program (not related to Codesoft) and built and deployed it (uses InstallShield single setup.exe if that matters). Previously, we did not have this problem, but on this build on certain PCs, when the Codesoft API is started, there is a 120 second delay, and the following exception is returned:
Application initialization failed with exception: Exception raised during initialization: Retrieving the COM class factory for component with CLSID {XXXX} failed due to the following error: 80080005 Server execution failed (Exception from HRESULT:0x80080005 (CO_E_SERVER_EXEC_FAILURE)).

...ANSWER
Answered 2020-Jul-13 at 23:05Solved. I was using the 2012 version of the API lppanet.dll in my build. That's why it worked on 2012 and not other versions (although the inconsistent operation on 2018 is odd). Using a higher level version works. I was thrown off by only having a dev license on 2012 (thinking that's the version that had been used previously, when it wasn't), and not being aware that it had been updated and wasn't forward compatible.

I am having a huge error with playing media files. This Media file in wrong encoding shows the problem I am having. My media player file looks very weird and that may be why my app is not working. For android studio is the media file suposed to have a playbutton or code because when I open up my media file it shows this:
...ANSWER
Answered 2017-Oct-11 at 02:22Android studio cannot play media files, so it opened the file as a text file. After all every files contains data in the form of bytes. If you open your media file with any other text editors, you'll see the same result.
If you open any other media files from Android studio, you'll get the similar result. So this is the expected behavior.

...ANSWER
Answered 2018-Sep-29 at 21:36What you are trying to do here is called Circular imports, which is something that is not supported by Python. You can read more about it here, in general, it means that it's not possible to have 2 files which are dependent on each other.
To solve that problem, all you have to do is to extract the resource both files need, to another file they can import from, for example:
