Dialog Position

[bobhibberdine2]

Hello,

Is there any way I can show either a custom dialog or a modal popup at any position I want?
The problem I have is that when the dialog is shown normally, it covers part of of the main window that the user needs to see!
I'd like the dialog to be modal as the main window need to ignore any user input while the dialog is shown.

Thanks!
Bob

Dialogs are positioned in a standard way but your app could add any overlay or popup and set the position of that.

Yes, I tried a normal popup (not modal) and I can position that anywhere I want. But then I need to add my own tap methods so that the popup does not get dismissed by a tap.
When I extend the popup to include the new behaviour the new methods do not get called!

I saw this discussion "Custom Popup Functionality #5340" which I think is relevant but I can't find the issue and resolution for this.
I am using version 2.74

Here's some demo code shows the problem:

package main

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

type tappablePopUp struct {
	widget.PopUp
}

func NewtappablePopUp(content fyne.CanvasObject, canvas fyne.Canvas ) *tappablePopUp {
 	pop := &tappablePopUp{}	
	pop.Content = content
	pop.Canvas = canvas
	pop.ExtendBaseWidget(pop)
	return pop
}

func (t *tappablePopUp) Tapped(_ *fyne.PointEvent) {
	println("I have been tapped")
}

func (t *tappablePopUp) TappedSecondary(_ *fyne.PointEvent) {
}

func main() {
	a := app.New()	
	w := a.NewWindow("demo")
	
	p := NewtappablePopUp(widget.NewLabel("demo"), w.Canvas())

	p.Show()
	w.Resize(fyne.NewSize(600, 800))
	w.ShowAndRun()		
}

On my Raspberry Pi 5 I never see the "I have been tapped"...

Thanks!

That sounds like a bug - though an unfortunately complicated one

[bobhibberdine2]

Ok, so I finally found the issue created from the discussion item #5340. It is issue #5358 and its resolution is in Commit 436a222.
But the additional code does not appear to be in fyne 2.7.4...

In any case the resolution would not really help me. What I would like to do is just override the Tapped functions of the popup.
Is this possible?

Many thanks...
Bob

Sorry for all this noise!!

What I said about the resolution for issue #5358 is wrong! The code is there. I was looking at a previous commit :-(
Sorry again.

I may be missing something - but what is wrong with NewModalPopup(...).ShowAtPosition(...)?

[bobhibberdine2]

Because ShowAtPosition calls Move() and it won't move the popup if its modal:

// Move the widget to a new position. A PopUp position is absolute to the top, left of its canvas.
// For PopUp this actually moves the content so checking Position() will not return the same value as is set here.
func (p *PopUp) Move(pos fyne.Position) {
	if p.modal {
		return
	}
	p.innerPos = pos
	p.Refresh()
}

That sounds like a bug to me. An exposed API should work as described :)

[bobhibberdine2]

Shall I make an issue of it, so to speak? :-)

[andydotxyz]

Yes please - easier to track progress than with a discussion
