Extended widget.Table not getting keyboard focus

[heejit]

I have extended the widget.Table to handle F2 key. clicking on table select the cell but pressing F2 key not trigger the event I have to press tab key before it work

package main

import (
	"fyne.io/fyne/v2"
	"fyne.io/fyne/v2/widget"
	"fyne.io/fyne/v2/container"
	"fyne.io/fyne/v2/app"

)


type TableWidget struct {
	widget.Table
	currentIndex widget.TableCellID

	data [][]string
}



func (this *TableWidget) onLength() (rows int, cols int) {
	rows = len(this.data)
	cols = 2
	return
}

func (this *TableWidget) onCreateHeader() fyne.CanvasObject {
	return widget.NewLabel("")
}

func (this *TableWidget) onUpdateHeader(pIdx widget.TableCellID, o fyne.CanvasObject) {
	if pIdx.Col == 0 {
		o.(*widget.Label).SetText("ID")
	}
	if pIdx.Col == 1 {
		o.(*widget.Label).SetText("Name")
	}

}

func (this *TableWidget) onCreateCell () fyne.CanvasObject {
	w := widget.NewLabel("-----------")
	w.Truncation = fyne.TextTruncateEllipsis
	return w
}

func (this *TableWidget) onUpdateCell(pIdx widget.TableCellID, o fyne.CanvasObject) {
	o.(*widget.Label).SetText(this.data[pIdx.Row][pIdx.Col])
}

func (this *TableWidget) onSelected(pIdx widget.TableCellID) {
	this.currentIndex = pIdx
}

func (this *TableWidget) TypedKey(event *fyne.KeyEvent) {
	this.Table.TypedKey(event)
	if event.Name == fyne.KeyF2 {
		println("f2 key pressed")
	}
}


func NewTable() *TableWidget {
	t := &TableWidget{}
	t.ExtendBaseWidget(t)

	t.data = [][]string{}
	t.data = append(t.data, []string{"1", "A"})
	t.data = append(t.data, []string{"2", "B"})

	t.Length       = t.onLength
	t.CreateHeader = t.onCreateHeader
	t.UpdateHeader = t.onUpdateHeader
	t.CreateCell   = t.onCreateCell
	t.UpdateCell   = t.onUpdateCell
	t.OnSelected       = t.onSelected
	t.ShowHeaderRow    = true

	return t
}


func main() {
	a := app.NewWithID("com.heejit.ui")
	w := a.NewWindow("UI")

	t := NewTable()
	t.SetColumnWidth(0, 50)
	t.SetColumnWidth(1, 150)

	l := container.NewBorder(nil, nil, nil, nil, t)
	w.SetContent(l)

	w.ShowAndRun()
}

is extended table's canvas not getting proper focus to receive keyboard event.

[heejit]

did i forgot to implement any method ?

It looks like there is a bug in table that it is not focusing extended versions of itself.

Try adding this to your custom table:

func (t *myTable) Tapped(e *fyne.PointEvent) {
	t.Table.Tapped(e)

	canvas := fyne.CurrentApp().Driver().CanvasForObject(t)
	if canvas != nil {
		canvas.Focus(t)
	}
}

it is working now thanks.

[andydotxyz]

Great thanks for confirming. It should also be fixed by applying PR #5596 which should make it to 2.6.0

Resolved on develop, will be in next release.
