How to set letter spacing of text in fyne-io/fyne?

In fyne-io/fyne, setting the letter spacing of text can be achieved by adjusting the style of text labels. Control the spacing between letters by setting the font and size of your text labels and using layout options. First, we need to create a text label and then use fyne.NewContainerWithLayout to set layout options. Next, we can use fyne.NewTextStyle to create a custom text style, and then use the SetStyle method to apply it to the text label. By adjusting the font size and letter spacing in the style, we can achieve the desired effect. In this way, we can easily set the letter spacing of text in fyne-io/fyne.

Question content

I used a custom font and the letter spacing looked too crowded.

I'm trying to change the letter spacing but can't find the configuration. So I want to modify the source code, but I don’t know where to set the letter spacing of the text?

Workaround

It's not set specifically anywhere, that's why you can't find it. This causes a mismatch between the old text rendering code and the new shaping code. This issue should be resolved by 2.4.0 when we move entirely to the new text rendering.

If you look at the source code you will see that the TextDPI internal constant is set to 78 but the shaper is 72DPI. Feel free to join our Slack or Discord server/room at https://www.php.cn/link/cf43a9e6874c5afbebe2858a64d45f52 to discuss more.
