NewButton.SetBorder(true) & NewButton.SetBackgroundColor(tcell.Color*[ANY]) results in a Button Text Wipeout Issue!?

[WhipMeHarder]

Hello Any/All, I have written some very simple code to test adding buttons to a tview Grid. However, when I try to change or customise the default attributes, the button text is automatically removed. Is there a way to prevent this, or a way to restore the original button text to the button so that it can be read? The original code when adding to a Grid is as follows:

app := tview.NewApplication() grid := tview.NewGrid(). SetColumns(3, 45, 3). SetRows(3,3,3,3). AddItem(tview.NewButton("Button 1"), 0, 1, 1, 1, 0, 0, false)

I want your attention on the last line:

AddItem(tview.NewButton("Button 1"), 0, 1, 1, 1, 0, 0, false)

The moment I change the code by adding any of the following styles to tview.NewButton, the visible text, "Button 1", is deleted, as follows:

AddItem(tview.NewButton("Button 1").SetBackgroundColor(tcell.ColorWhite), 0, 1, 1, 1, 0, 0, false). - Any color substituted has the same effect.

Or,

AddItem(tview.NewButton("Button 1").SetBorder(true), 0, 1, 1, 1, 0, 0, false). - Also removes the visible text, "Button 1", from the button object.

Is there a remedy for this issue?

SetBackgroundColor() returns a Box, not a Button. Some details on this here: https://pkg.go.dev/github.com/rivo/tview#hdr-Type_Hierarchy

The solution would be something like this:

button := tview.NewButton("Button 1")
button.SetBackgroundColor( ... )
grid.AddItem(button, ... )

Ok. Yes! This works! The reason being, that chaining functions which belong to the same primitive may not necessarily be a subclass of it.
