Is there a widget reference for fyne? I want to see a demo of the widgets without downloading/installing fyne.

i would like to make some changes in the css files but i don't understand how do i start the development server in my computer
please help me to start the server or give me the commands to start the server

my OS: win 10
NOTE: i've already install ruby on machine

On mobile devices page https://developer.fyne.io/ div "intro row" overflows horizontally if screen width is less than 675. This is most likely caused by div.intro-row having flex-flow with no-wrap property.

Description

When the fyne size is changed (Non-Normal size) by fyne_settings, the image size and font size are changed, however the window size will not be changed.
This happens with the image being resized with the original image size and "FillMode = canvas.ImageFillOriginal".

Below is a program that reproduces this bug.
Execute the following program after changing the size to "Tiny" size instead of "Normal" size with the fyne_settings command.

package main

import (
  "os"
  "image"
  "fyne.io/fyne/v2"
  "fyne.io/fyne/v2/app"
  "fyne.io/fyne/v2/canvas"
  "fyne.io/fyne/v2/container"
  "fyne.io/fyne/v2/widget"
)

func loadImage(imgFile string)*canvas.Image{
  if file,err := os.Open(imgFile); err == nil{
    defer file.Close()
    if img,_,err := image.Decode(file); err == nil{
      cnvsImg := canvas.NewImageFromImage(img)
      cnvsImg.FillMode = canvas.ImageFillOriginal
      cnvsImg.Resize(fyne.NewSize(float32(img.Bounds().Dx()), float32(img.Bounds().Dx())))
      return cnvsImg
    }
  }
  return nil
}

func main() {
  if len(os.Args) == 2{
    app := app.New()
    if img := loadImage(os.Args[1]); img != nil{
      win := app.NewWindow("Image Viewer")
      label := widget.NewLabel(os.Args[1])
      cntr := container.NewWithoutLayout(img)
      win.SetContent(container.NewVBox(cntr, label,))
      win.ShowAndRun()
    }
  }
}

How to set the similar desktop minimize icon

This very first fyne example in the API documentation does not compile because the package widget has no function NewVBox.

    package main

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

    func main() {
    	a := app.New()
    	w := a.NewWindow("Hello")

    	hello := widget.NewLabel("Hello Fyne!")
    	w.SetContent(widget.NewVBox(
    		hello,
    		widget.NewButton("Hi!", func() {
    			hello.SetText("Welcome :)")
    		}),
    	))

    	w.ShowAndRun()
    }

Looks like there's a problem with the documentation generator as https://developer.fyne.io/api/v2.1/theme/ is pretty empty.

I'm leaning go and i'm readning fyne toturial, the border layout example at here is little not clear, i think you should use button widget replace the original white label text.

Tried out this lib today but it seems like there is a deprecated warning for the macos dependencys?

it has been 2 day no one reviewed my pull request.

Hi there,
I am working on some app to connect musicians with extremely low delay over the internet.
I am attaching a working proposal that would allow handling generic elements in Select widgets.
Keep it up, this is a fantastic library!!
Claudio

package widgets

import (
	"fmt"
	"fyne.io/fyne/widget"
)

type Anything interface {}

type SelectInfo struct {
	Widget   *widget.Select
	infoMap  map[string]Anything
	callback func(string)
	stringer func(Anything) string
}

func NewSelectInfo(
	stringer func(Anything) string,
	changed func(Anything)) *SelectInfo {

	c := &SelectInfo{
		stringer: stringer,
		infoMap:  make(map[string]Anything),
	}

	c.Widget = widget.NewSelect(
		make([]string, 0),
		func(s string) {
			changed(c.inverseStringer(s))
		})

	return c
}

func (c *SelectInfo) Selected() Anything {
	return c.infoMap[c.Widget.Selected]
}

func (c *SelectInfo) Reset() {
	c.Widget.Options = make([]string, 0)
	c.infoMap = make(map[string]Anything)
}

func (c *SelectInfo) LoadInfo(x Anything) error {
	key := c.stringer(x)
	_, found := c.infoMap[key]
	if found {
		return fmt.Errorf("key:[%s] already in the map", key)
	}

	c.infoMap[key] = x
	c.Widget.Options = append(c.Widget.Options, key)

	return nil
}

func (c *SelectInfo) SelectInfo(x Anything) {
	c.SelectText(c.stringer(x))
}

func (c *SelectInfo) SelectText(s string) {

	if len(c.infoMap) == 0 {
		return
	}

	_, found := c.infoMap[s]
	if !found {
		c.Widget.SetSelectedIndex(0)
	}

	c.Widget.SetSelected(s)
}

func (c *SelectInfo) inverseStringer(in string) Anything {
	v, _ := c.infoMap[in]
	return v
}

Is your feature request related to a problem? Please describe:

In the tutorials, there should be an example of customizing button colors.

Is it possible to construct a solution with the existing API?

Yes

Describe the bug

I wanted to try out fyne and used the form example from here.

Building and running it gives me this UI, where I can only see the first column of the form, see screenshot.

How to reproduce

1. build example code
2. run it
3. only one column gets rendered
4. resizing or moving the app window doesn't help
5. inspecting the code it looks like a bad combination of default background color and label foreground color - both seem to be white, making the rendered values invisible !
6. Fixing the colors ( color.RGBA{0xff, 0, 0, 0xff} instead of color.White ) in the code still renders odd form layout, rows doesn't seem to get aligned vertically.

Screenshots

With the white background/foreground

With other foreground, still rendered odd:

Example code

Copy from the example page:

package main

import (
	"image/color"

	"fyne.io/fyne/v2/app"
	"fyne.io/fyne/v2/canvas"
	"fyne.io/fyne/v2/container"
	"fyne.io/fyne/v2/layout"
)

func main() {
	myApp := app.New()
	myWindow := myApp.NewWindow("Form Layout")

	label1 := canvas.NewText("Label 1", color.Black)
	value1 := canvas.NewText("Value", color.White)
	label2 := canvas.NewText("Label 2", color.Black)
	value2 := canvas.NewText("Something", color.White)
	grid := container.New(layout.NewFormLayout(), label1, value1, label2, value2)
	myWindow.SetContent(grid)
	myWindow.ShowAndRun()
}

What:
Example code: https://developer.fyne.io/tour/basics/windows.html

Environment:
Fedora 33
go version go1.15.8 linux/amd64

Problem:
After closing main window the program seems to still run.

Steps:

1. Paste code into a file (ie. test.go)
2. Run code: go run test.go
3. Wait for second window to show up and dissapear
4. Close main window

Result:
Even after closing the window, the console is not released and the process lingers:

trochej 72955 2.3 0.0 1750860 23404 pts/1 Sl+ 20:39 0:00 go run test.go
trochej 73054 4.3 0.2 1960936 67304 pts/1 Sl+ 20:39 0:00 /tmp/go-build574735481/b001/exe/test

Example prog here: https://github.com/fyne-io/developer.fyne.io/blob/master/api/v2.0/index.md

still references widget.NewVBox -> container. of course

:)

Describe the bug

I followed the command described on https://developer.fyne.io/started/#run-the-demo

Since the text says "If you want to see the Fyne toolkit in action before you start to code your own application", I (wrongly) assumed I did not have to do / install anything first.

This is the output from my computer executed in folder 'temp':

➜ temp go run fyne.io/fyne/v2/cmd/fyne_demo
no required module provides package fyne.io/fyne/v2/cmd/fyne_demo: go.mod file not found in current directory or any parent directory; see 'go help modules'
➜ temp go version
go version go1.18 darwin/arm64

Later on I realised that the author meant that I had to do the steps described in Downloading section first. You need to take the phrase 'to code' literally.

However if you execute go mod tidy - it will remove the required fyne dependency since there is no Go file referencing it.
If you skip go mod tidy, so the dependency is there, you are also out of luck since there is no go.sum file.

So after repeating the steps in the Download section, I got the following error message:

➜ temp go run fyne.io/fyne/v2/cmd/fyne_demo
no required module provides package fyne.io/fyne/v2/cmd/fyne_demo; to add it:
go get fyne.io/fyne/v2/cmd/fyne_demo

If you execute above go get command, it works.

A solution is to move the Installing section up, as first part of Running the demo.

I propose that we add a page for displaying the icons that exist within the theme package. A bit like how we do for layouts, but for icons instead. This would make it easy for users to see what icons exist and then pick the one that suits their use case.

I have been trying to run this as the instruction suggest in my ubuntu with ruby 3.2 and using the docker image of jekyll and I am getting loads of issues:

on docker:

The entry reads:

ShowEntryDialog creates a new entry dialog and shows it immediately.

Deprecated: Use dialog.ShowFormDialog() with a widget.Entry inside instead.

There is no dialog.ShowFormDialog(). The reference should be to dialog.ShowForm()

It is go get fyne.io/[email protected] and it should be go get fyne.io/fyne/[email protected]

-works after "go run . 12" and click
