Describe the bug

I'm trying to work with TextGrid to craft an editor. But I sometimes getting this error at the start of the app. I just need to restart the app for it to disappear. It seems to only appear if I close the app abruptly with the stop button from Goland.

Any idea what's going on ? I'm running Linux.

How to reproduce

1. Having a widget using a TextGrid.
2. Close the app abruptly (Ctrl+C in term or Stop in Goland)
3. Rerun the app
4. It'll happens sometimes

Example code

type Editor struct {
	widget.BaseWidget

	Grid *widget.TextGrid

	CurrentRow int
	CurrentCol int
}

func NewEditor() *Editor {
	editor := &Editor{}

	editor.Grid = widget.NewTextGrid()

	editor.CurrentRow = 0
	editor.CurrentCol = lineStartCol

	editor.Grid.ShowLineNumbers = false
	editor.Grid.ShowWhitespace = false

	editor.ExtendBaseWidget(editor)

	return editor
}

func (e *Editor) CreateRenderer() fyne.WidgetRenderer {
	return widget.NewSimpleRenderer(e.Grid)
}

Can you please provide a fully runnable code example and also specify what error you are getting? That makes it a lot easier for us to test.

Hi,

Of course, here it is with another kind of possible random error. Hope it helps.

I just want to say that's it's a lot of effort to use those TextGrid. I looked in detail of what you guys did for the Fyne terminal, which is amazing by the way.

Maybe at looking at this little piece of code, you could give me some advice and even giving some insight on the why TextGrid are capable to resize the window size when growing in size ? It's blowing my mind.
Actually, just try to manually resize the window in this simple demo. It's slow as hell. I don't understand why I must say.

Thanks for you precious help.

For an editor I would recommend using the Entry widget (probably with monospaced style set).

Any widget will cause the window to expand if their min size is larger than the window allows.

That’s very interesting.
