added this to the 1.3 - File dialog, notifications, many new widgets milestone

I cannot replicate this on the same hardware. |
|
Edit: Forgot to say I'm on Windows I encountered a similar error when using this code, and resizing the window I have a suspicion it is something to do with my display
Here is the code package main
import (
"fyne.io/fyne/widget"
"fyne.io/fyne/app"
)
func main() {
app := app.New()
w := app.NewWindow("Hello")
w.SetContent(widget.NewVBox(
widget.NewLabel("Hello Fyne!"),
widget.NewButton("Quit", func() {
app.Quit()
}),
widget.NewButton("New Window",func() {
w2 := app.NewWindow("Another Window")
w2.SetContent(widget.NewLabel("Hello again!"))
w2.ShowAndRun()
}),
))
w.ShowAndRun()
}Console outputrohan@DESKTOP-Q4LRFRP MINGW64 ~/source/repos/GoApp $ go run main.go 2020/06/01 14:57:02 PlatformError: WGL: Failed to make context current Exception 0xc0000005 0x0 0x37d0 0x7ffcc7b5c638 PC=0x7ffcc7b5c638runtime: unknown pc 0x7ffcc7b5c638 goroutine 18 [syscall]: goroutine 1 [syscall, locked to thread]: goroutine 6 [sleep]: goroutine 7 [chan receive]: goroutine 8 [syscall, locked to thread]: goroutine 9 [chan receive]: goroutine 19 [chan receive]: goroutine 10 [chan receive]: goroutine 34 [chan receive]: goroutine 35 [chan receive]: goroutine 21 [chan receive]: |

The screenshot you provided looks like it's not running our 'develop' branch which means a lot has changed already. We re-wrote quite a bit of scale and resize/paint handling. |
|
I already have the master branch version of Fyne installed. Will I have to remove my existing Fyne install? Also, can you guide me towards instructions to install the latest develop branch? Thanks. |
|
You do not have to remove it, you can install over the top. The following should be sufficient for an existing installation: cd $GOPATH/src/fyne.io/fyne/cmd/fyne
git checkout develop
git pull
go installThen run fyne_demo again and you should see it has different tabs. Let us know if this changes the situation. |
|
It looks like the parameters are valid and that it's running on the right thread - might need a bit more digging at your send to inspect the values to see which is corrupting or causing unexpected state? |

The fyne_demo looks good. The buttons are a little too big. I'm not too sure how the scaling works, but maybe it is possible to change the scale based on screen resolution? The code that I wrote in my previous comment crashed with a different error message, and it didn't crash when I resized it, it crashed immediately after opening a new window. package main
import (
"fyne.io/fyne/app"
"fyne.io/fyne/widget"
)
func main() {
var app = app.New()
var w = app.NewWindow("Hello")
w.SetContent(widget.NewVBox(
widget.NewLabel("Hello Fyne!"),
widget.NewButton("Quit", func() {
app.Quit()
}),
widget.NewButton("New Window",func() {
var w2 = app.NewWindow("Another Window")
w2.SetContent(widget.NewLabel("Hello again!"))
w2.ShowAndRun() /*will crash*/
}),
))
w.ShowAndRun()
}Console Outputrohan@DESKTOP-Q4LRFRP MINGW64 ~/source/repos/GoApp (master) $ go run main.go panic: Run() or ShowAndRun() must be called from main goroutinegoroutine 34 [running]: |
|
Don’t call ShowAndRun() a second time, use just Show(). |
|
If you want things to be a little smaller then run the included fyne_settings app and choose “smaller” :) |
|
Thanks, but for some reason I was not able to run fyne_settings from my terminal. I had to go into /go/src/fyne.io/fyne/cmd/fyne_settings and do |

modified the milestones:
1.3 - File dialog, notifications, many new widgets,
1.3.x
|
Reports are that this does not happen since 1.3.0 according to @toaster |

Not sure if this is right the issue for this, but fyne v2.1.1 still crash on macOS when resizing windows. EDIT: 2.1.2 seems to fix it |
Are you on an M1 machine by any chance? A similar issue should have been fixed with v2.1.2, which currently is the latest release. |
Yes, M1, just tested with 2.1.2, seems working, updated my first post |
When resizing a window on MacOS (10.14) a Fyne app (e.g. fyne_demo) eventually crashes:
