How do I capture {Enter}/257 on a InputText?

[rbeer]

I want to call a function when the {Enter} key is pressed in a simple - not multiline - InputText.

I've been trying all sorts of combinations:

.Callback() - I see keys pressed and the EventChar(), but {Enter} blurs the InputText and never fires the event that would have EventChar() == 257

g.Layout{
  // flags and correct func signature omitted for brevity
  g.InputText("Symbol", &p.Symbol).Callback(func(d) {
    fmt.Println(d.EventChar())
  }),
}  

.Custom() with IsKeyPressed(257) - I get the event, but everywhere; even when InputText doesn't have focus.

g.Layout{
  g.InputText("Symbol", &p.Symbol),
  g.Custom(func() {
    if g.IsKeyPressed(257) {                                                                                                                                                                                            
       fmt.Println("Enter Pressed")                                                                                                                                                                                     
    }
  }),
}  

.Custom() with IsKeyPressed(257) and IsItemActive() - does nothing, at all

g.Layout{
  g.InputText("Symbol", &p.Symbol),
  g.Custom(func() {
    if g.IsItemActive() && g.IsKeyPressed(257) {                                                                                                                                                                                            
       fmt.Println("Enter Pressed")                                                                                                                                                                                     
    }
  }),
}  

I don't understand how the Events work, really. What for example is Item in IsItemActive?

This is really tricky in imgui. I will try to figure it out later.

Oh, ok. I'm fairly new to Golang overall so I thought I was just missing something. No need to put this high up your list, since I've found a whole other way to get the desired input using the clipboard:

g.Child("Trigger").Size(-1, 100).Layout(                                                         
  g.Label("Trigger:"),            
  g.Checkbox("Arm", &armed).OnChange(func() {                                              
    if armed {                                                                       
      go func() {     
        armedCtx, armedCancel = context.WithCancel(context.TODO())       
        ch := clipboard.Watch(armedCtx, clipboard.FmtText)               
        for data := range ch {
          p.SetSymbol(string(data))                            
          p.Fire(c)                                                
          g.Update()          
        }                                                                
      }()             
    } else {                
      armedCancel()                                                            
    }                       
  }),                                                                                      
  g.Tooltip("Watches the clipboard and executes on next text copied into it.\nThere will be no further confirmation!"),                                                                                                           
  g.Condition(armed, g.Layout{
    g.Label(fmt.Sprintf("Watching clipboard for symbol: %s", p.Symbol)),    
    g.Label("BE CAREFUL WHAT YOU COPY NOW!").Color(&color.RGBA{0xff, 0x00, 0x00, 0xff}),                                                                                                               
  }, nil),                        
),             

I will eventually get back to this and of course post if I figure something out.

@rbeer Can you tell me more about your case and I might be able to provide more help here. :P

[rbeer]

1. Left side, where the Servers are listed, first icon "Home"
   2.1. "Find or start conversation" text field
   2.2. Or the + at "Direct Messages"

Should bring up my user

[rbeer]

Oh wait; I need to allow users I dont share servers with :)

[rbeer]

Should work now

[AllenDang]

Still cannot find...

[rbeer]

Ok, try this one: https://discord.gg/UZFkGxjh

Created a server you can just join

[gucio321]

@rbeer what about this?

package main

import (
	"fmt"

	"github.com/AllenDang/giu"
)

var out string

func loop() {
	giu.SingleWindow().Layout(
		giu.InputText(&out),
		giu.Event().OnKeyPressed(giu.KeyEnter, func() {
			fmt.Println("enter pressed")
		}),
	)
}

func main() {
	wnd := giu.NewMasterWindow("wnd", 640, 480, 0)
	wnd.Run(loop)
}
