Tables with too many rows will not fit. When a row outside view is selected the scroll area should offset the view to include the selected row.

For comparison: Qt has a QScrollArea that decorates a widget with scrolling functionality.

This would be very nice combined with mouse support :)

Example:

t := tui.NewTable(0,0)
a := tui.NewScrollArea(t)

User need to be able to change focus from one widget to another, e.g. between OK and Cancel buttons.

tui should be able to construct a default focus chain that can be overrided.

Cycling widgets should probably be done with Tab and Shift-Tab.

Hi, is it already possible to add keybindings with the ModKeys?

If so I can't figure how from the docs and examples.

I see SetKeybinding takes (inter{}, func ).

How are ModKey events handled?

I've got a panel in my app that I'd like to draw with reversed colors. The way I've come up with to handle this is to embed the tui.Box in a custom struct, and override Draw with a custom function:

func (c *custom) Draw(p *tui.Painter) {
  p.WithStyle("reversed", c.Box.Draw)
}

But, this doesn't work if the Box contains Spacer widgets - which still render using the default background. I'd expect them to be filled with the current background color, if I'm understanding the intended semantics of Draw and WithStyle correctly. (Is that the intended behavior?)

Full example gist; I'm expecting a line across the whole thing.

It looks like Spacer inherits the default WidgetBase Draw function, which is blank. I'm not sure if the default Draw should fill its background, or whether this should just apply to Spacer; I see #45 has a maybe-related commentary on Box.

(All that said, tui is great to work with; looking forward to its future. :-) )

I'm looking to have 2 different components that can be toggled, where they both occupy the same space (a bit like a tabbed interface would). Is this currently achievable? I didn't notice show/hide methods on widget so assumed not.

List items can be added but not removed. Since the items are a simple []string a Clear() method would be a fairly straight forward approach, knowing items will have to be re-added if only one item is being cleared.

painter_test.go has a nice implementation of the Surface interface for testing writes.

It would be nice to factor that out so tui users can test their own layouts or custom Widgets.

I think I finally got this nailed down. Issues were mostly related to masking rather than the scroll area itself. More specifically due to not having clearly defined what a zero mask meant.

A key insight was to make sure that a mask needs to be defined at the root level, based on the size of the Surface.

Closes #40.

First sorry if I bother you with so many questions!

I'd like to have different font colors in my list ('ala tig tool) using something like https://github.com/fatih/color#insert-into-noncolor-strings-sprintfunc, e.g:

// ...
yellow := color.New(color.FgYellow).SprintFunc()
red := color.New(color.FgRed).SprintFunc()
return fmt.Sprintf("%s|%s|o %s", b.Author.When.String()[2:19], yellow(author), red(name))
// then I use the returned string as en element for `list.AddItems()

Unfortunately color codes are not rendered:

Any idea if this is possible? (-:

Hi! I'm not sure if this changed recently, because after updating the lib I found my scroll areas were only displaying 8 rows.

The docs for the ScrollArea.SizeHint method suggest it is meant to return "the size hint of the underlying widget."

This PR is doing just that 😄

ref #20

I think this follow the direction given in the ticket. I had to increase the widget interface to add a method called IsFocused() bool.

The example app works fine and looks ok except for the Login. For some reason the text SKYNET is also blue when the focus is on the buttons. I don't think it should be the case.

There is still a bit of work but I would appreciate some feedback to let me know if I am on the right track.

• [x] is the blue line to thick for the default the style box.selected if so how to decrease it ?
• [x] Fix the login example
• [x] write a test or 2

Hey! Just saw your project and noticed the "Update" in the readme.

If you're no longer going to be maintaining the project, I'd recommend archiving it, unless you have a reason for keeping it active as it is currently.

That's it.

Thanks for putting your time and effort into something like this!

I've been writing a program which has many lists, for which the style is required to be different for some lists (highlighting can occur between lists)

This PR basically, allows for a new "root" style of a list object to manually changed however still following the pattern of <yourstyle> for the default and <yourstyle>.selected for the selected box.

This PR is backwards compatible with no interface changes

Open to suggested design alternatives!

type TableEx struct {
	*tui.Table

	Style string
}

func (t *TableEx) Draw(p *tui.Painter) {
	p.WithStyle(t.Style, func(p *tui.Painter) {
		t.Table.Draw(p)
	})
}

It just make custom table.cell style, but how do i replace the table.cell.selectedstytle?

This is my code:

history.Append(tui.NewHBox(
		tui.NewLabel(time.Now().Format("15:04")),
		tui.NewPadder(1, 0, tui.NewLabel(fmt.Sprintf("<%s>", "john"))),
		tui.NewLabel(message),
		tui.NewSpacer(),
	))

In fact I am trying the "chat" example, and read data from a TCP connection, then write to the "history", but it not works.

Hello. I use your framework to develop a TUI file dialog, "tfd". This framework is great! But seems to have one bug. Apps created using this framework will not release CPU resources even if exit with ui.Quit().

For example, if you put time.Sleep(time.Second*10) in the last line in tui-go/example/login/main.go, you can confirm that the CPU resources are not released.

I don't know the details of this framework, but I thought this bug is caused by the for-loop in ui.Run() being kept running.
