Glad to hear that you managed to get it working

Hello & welcome to the µGFX community!

That's not correct, see below.
1 minute ago, SlowGoing said:I keep getting compiler error "undefined reference to `gwinGLabelCreate'"
What am I missing ?
Did you enable the label widget in the configuration file?
If that's not the case you're most likely not including all files properly. -
Hello & welcome to the µGFX community!
Please excuse the late reply.
This issue has been fixed now. There seemed to be a caching issue with the SSL cert where the SSL cert did get renewed but not properly cached.
Your account has also been activated.Thank you for bringing this to our attention!

Sorry, I do not understand your question.

Glad to hear that you got everything working

Did you have a look at this? https://wiki.ugfx.io/index.php/FreeRTOS
Also make sure that you're using the latest master branch.

It seems that you're confusing transparency and alpha-channel.
If you're using GIF then that's expected as GIF doesn't support alpha buy only transparency.
If you're using PNG you should refer to the documentation: https://wiki.ugfx.io/index.php/Images#Alpha_.26_Transparency -
Hi,
You just need to use an image format which supports transparency. The existing GIF and PNG image decoders will handle transparency out of the box.

Hello @chrisdf and welcome to the µGFX community!
Thank you very much for sharing your experience here. We appreciate it a lot and I'm sure it will help countless people in the future as well! This is definitely interesting.

Hi,
Thank you for your feedback. Both these points have already been added to the ToDo/bug list.

Released v0.23.2 that fixes the 480x640 pixel placement issue.

Issue where the maximum display size couldn't be larger than 640 x 480px,
not FIXED.
All widgets whose y-axis coordinates are greater than 480, after loading the project, are located above this coordinate.We'll investigate this.

Added to the ToDo list.

Thank you, inmarket and Joel! I have now implemented the fillrect function used in the Adafruit library as GDISP_HARDWARE_FILLS, and indeed, it is much faster now. All in all, I'm quite happy with the performance: Clearing the screen with a certain color takes 33ms on the ESP32 using SPI.
Nice, glad to hear that you got everything working!
We'd appreciate it if you could create a ready-to-run example for the downloads page and maybe some documentation for the wiki.12 hours ago, Paul Christopher said:What would be a good example in the code base to test whether multithreading / scheduling really works with my patch?
Have a look at /demos/gos.
12 hours ago, Paul Christopher said:Is this the time for me now to dive into GWIN? Or for what is the ugfx scheduler actually used?
The scheduler is also used for things like GTIMER which in turn is used by GINPUT and GWIN. As mentioned above, /demos/gos should help.

Version 0.23.1 has just been released. Changelog:
- Updating About dialog
- Changing default font generator size from 8px to 16px
- Fixing issue where console widget isn't loaded from project file
- Fixing issue where the visible attribute affected the enable attribute
- Fixing issue where the generated calibration code contains syntax errors (missing commas)
- Fixing an issue where the maximum display size couldn't be larger than 640 x 480px
- Fixing an issue where using the mouse wheel on the zoom slider didn't update the actual zoom factor
- Fixing some resource files issues
- Fixing issues with dialog box close events
- Adding new bugs with dialog box close events to fix later
-
I'd recommend you to have a look at the buffer in the GConsoleObject object (cast from GHandle).

The reading are very responsive though not much accurate on the four angles of my touch screen.

1 hour ago, krisPainkiller said:I've also tested the touch_driver_test demo using its tunings and calibrations but the readings aren't responsive at all. It is very difficult to calibrate the touch screen with this demo for me.
What do you mean by "not very responsive"? What's the behavior in a regular GWIN application like?
-
That's interesting.
Could you please leave some detailed information of the compiler you're using and also your build flags?
4 hours ago, Rafael Zingler said:This problem only happens when I use the console during startup.
What does that mean? Can you please give some more details?

Have a look at the /demos directory. Especially /demos/tools in your case.

Nice, much appreciated!

Welcome to the µGFX community!
Happy to hear that you managed to get things up and running

Hello and welcome to the µGFX community!
Unfortunately, there isn't an existing GINPUT driver for that touch screen controller. However, it's very easy to add a new one. Take the existing drivers as an example. You can simply copy the one who matches your controller the best (eg. don't take the ones which use the microcontroller's ADC to determine the touch coordinates) and modify from there.
The entire driver interface is well documented in the corresponding GINPUT documentation.Please don't hesitate to ask if you have any questions - we're happy to help wherever we can!
-
Thank you for bringing this to our attention. I've modified the documentation accordingly.

Use radio widgets with the button draw routine.
Correction: Use the checkbox widget, not the radio widget.

We don't have any fixed release cycle. We can basically release at any time. I guess we can fire something up this or next week.

Unless I'm misunderstanding you that should already exist (and work). Select multiple items and have a look at the context menu.

gmvmt is a VMT (virtual method table). calsave is a function pointer in that table. Your custom saving routine is registered there. Therefore, gmvmt(m)->calsave() will call your custom saving function.
If you get a hard-fault at that point your function is either not properly registered (wrong address?) or the implementation of your own function is causing the hardfault. Step into that function to check which one is the case.
