Error gfxglyph does not name a type

I just built the GLUE_Demo_480x320 example from the v2.9.7 Release on GitHub.
However, I am actually using the Master Branch currently on GitHub (Beta).

It built and ran on Mega2560. I commented the undef. It built and ran on the Mega2560.
It is difficult to distinguish between the FreeSmallFont and the regular Adafruit 7×5 system font.

If you are an ordinary Arduino user:
I strongly recommend that you delete any old directories and install a «Release» with the Library Manager.
There is seldom anything to be gained by using the latest Beta. (unless it is some new unseen hardware)

If you are a GitHub member and have cloned/forked a Repository, you can use GitHub to select any historic release. But please say exactly what release you are using.

Works, Thanks ;]

but I didn’t set a BACK color
tft.setBackColor(YELLOW);
tft.setTextColor(GREEN, YELLOW);
on Adafruit 7×5 font work good

The FreeFonts only render as transparent. You have to re-paint any background colour before printing.

From memory, I kludge rubout printing with the UTFTGLUE class.

One day I might offer rubout printing but this would violate all the GFX tutorials and documentation.

David.

pls help quickly
i use utftglue.h file but i can’t use the font.

how i resolve this problem.

Run the GLUE_320x240 demo. Observe the Title font. Especially the width.
Then edit UTFTGLUE.h to comment the #undef line.

Run the GLUE_320x240 demo. Observe the different font.
Most UTFT example sketches will work with the UTFTGLUE class.

If you have a problem, quote which UTFT example. I will help you.
If you have a new project, you would use the native GFX methods instead of UTFTGLUE.

If you have a general problem with your project, it is better to attach files, ask questions on the Arduino.cc Displays Forum. GitHub is for library source code or usage questions.

David.

thank you very much!
but how i use custom or other fonts ??
