How to reset internal "state" for inputtextmultiline and maybe other widgets?

[deoxyimran]

The internal "state" system is causing some headache. It seems the previous text is carried over the next frame. So I gave unqiue IDs. Now suppose the multiline text widget is "destroyed", how do I now reuse the id (or label) for a new multiline text widget as the previous state is still retained? Is there anyway to clear all the previous state of the widget by say their ID...and start a new widget with same ID? This is also useful when i want to clear all the text already present in the text widget.

Try this:

package main

import (
    "github.com/AllenDang/giu"
)

var (
    currentIdx string = "id1"
    data              = map[string]*string{
        "id1": new(string),
        "id2": new(string),
        "id3": new(string),
    }
)

func loop() {
    giu.SingleWindow().Layout(
        giu.InputTextMultiline(data[currentIdx]),
        giu.RangeBuilder("switcher", []string{"id1", "id2", "id3"}, func(_ int, s string) giu.Widget {
            return giu.Button(s).OnClick(func() { currentIdx = s })
        }),
    )
}

func main() {
    wnd := giu.NewMasterWindow("Clean Input Text Multiline [discussion #866]", 640, 480, 0)
    wnd.Run(loop)
}
