gowd's Issues

Example of FileButton

Hi,
Can you give an example of how to use FileButton to receive a selected filename in gowd?

I have tried:

package main

import (
	"github.com/dtylman/gowd"
	"github.com/dtylman/gowd/bootstrap"
	"fmt"
)

var body *gowd.Element

func main() {
	//creates a new bootstrap fluid container
	body = bootstrap.NewContainer(false)
	// add some elements using the object model
	div := bootstrap.NewElement("div", "well")
	row := bootstrap.NewRow(bootstrap.NewColumn(bootstrap.ColumnSmall, 3, div))
	// add a button to show a progress bar
	btn := bootstrap.NewFileButton(bootstrap.ButtonPrimary, "Upload File", false)
	btn.OnEvent(gowd.OnChange, btnFileUploaded)
	div.AddElement(btn.Element)
	body.AddElement(row)
	
	//start the ui loop
	gowd.Run(body)
}

// happens when the file is added to the FileButton above
func btnFileUploaded(sender *gowd.Element, event *gowd.EventElement) {
	body.AddElement(gowd.NewStyledText(fmt.Sprintf("Selected %s", sender.GetValue()), gowd.BoldText))
	body.AddElement(gowd.NewElement("br"))
}

and no filename is shown when I select a file.
I also tried:

// happens when the file is added to the FileButton above
func btnFileUploaded(sender *gowd.Element, event *gowd.EventElement) {
        fileButton := sender.Object.(*bootstrap.FileButton)
	body.AddElement(gowd.NewStyledText(fmt.Sprintf("Selected %s", fileButton.GetValue()), gowd.BoldText))
	body.AddElement(gowd.NewElement("br"))
}

and this also failed.

Possible to pack nw.js into go executable as one executable file use packr or statik

process exited with code -2

I keep getting process exited with code -2 every time I run "nw .", this is just with the template as I haven't changed anything yet.

Bundle nwjs during build for a standalone executable?

Hi, pardon my inexperience. Looks like this project requires nwjs installed to run?

I like go in that it can build self contained binaries that tend to also be small footprint. It would be nice for future enhancement to build scaffolding on top of this project such that you can bundle the nwjs requirement into the compiled go binary so that instead of

nw . in the current path where the code is compiled, we could do ./myGoAppName, and where we can use go build and go install (or some other final build process) on the scaffolding to produce a standalone self-contained binary that will run w/o installing nwjs for it is packaged in with the compiled app.

Initially this could just target the platform being built on, and later look into cross-compile support (compile once and you get binaries for *nix, Mac, Windows).

For me, w/o the self contained binary feature, I don't see that much benefit of go w/ nwjs, I could just use other language with it instead.

Window size

Can you set the size of the window when it opens?

Strip CRLFs when parsing HTML

passing line breaks in side innerHTML param to ParseElement causes line breaks to appear in the generated output, causing malformed UI to be passed to nwjs.

When I try to run the todomvc code, I get "Process exited with code -4058".

I am also having a separate error but I understand that it is not harmful:

MINGW64 ~/go/src/github.com/dtylman/gowd/cmd/todomvc (master)
$ ~/nw/nw .
[10864:5888:0303/195421.396:ERROR:device_event_log_impl.cc(211)] [19:54:21.396] USB: usb_device_handle_win.cc:1049 Failed to read descriptor from node connection: A device attached to the system is not functioning. (0x1F)

how to solve gowd is easily cracked

For which operating systems is this available ?

I assume that because of nwjs it is for the big three : Linux, OS X and Windows.
Just looking for confirmation.
Thanks already.

Cannot set text of a text area.

Hello,

First off, I would like to say that I am glad I found this library because I really like it.

Now, my issue is that whenever I try and set the text of a textarea element using element.SetText(), it will clear all my elements(the body). I am not sure why this happens but thought that maybe you could look into it.

Thanks!

Very confused by installation intructions

Hey!

I want to use NW.js in my Go project, but I have absolutely no experience from installing it. I am very confused by the steps in your installation instruction. Would be great if you could write an ELI5 version of it.

Cheers!

<select> element on event changes to first option.

I'm developing a GUI app on go

div = gowd.NewElement("div")
div.AddHTML( Seleccione...100200300, b.em) pnl.AddToBody(div) b.em["lstEmpresas"].OnEvent(gowd.OnChange, b.onChangeLstEmpresa) i have 3 value in a select element, when the onchange event is called works and i can get de option... But when the event finishes, the option is changed to the first option. How i can solve this issue?

Adding tag item for elements

Will add a tag interface{} for each element so users can associate arbitrary data to elements.

how to use gowd and keygen together?

In your third example code with gowd, the HTML dropdown is not working. I am including a screenshot of what I get, in case it helps.

feature request, possible to use a golang package to automatically download nw.js in different machine platform and use remote url as gui just like go-astilectron and go rod

能否介绍一下在mac上怎么打包windows app

我用的是mac，想要给mac ，liunx 和 window 打包程序，具体该怎么操作呢，感谢

Request to move repo under NW Userland

Hi @dtylman,

I'm a member of NW Utils. I'm trying to consolidate NW tooling so it's easier to find useful projects and give much needed life to stagnant ones.

Hope to chat soon!
