When trying to compile rod with nake, I have the following error:
/home/wan/.nimble/pkgs/nimx-0.1/nimx/font.nim(16, 15) Error: cannot open 'private/edtaa3func'
Maybe it's a file that hasn't been committed to the nimx repo?

Is this component ready?

TextField allows writing over the bounding border , it is not clear from the test sample programs
how to limit this. I think the behavior should be horizontal scrolling within the border of the
TextField.

I am using MSYS2+MingW64 on Win7 64 bits. But $ ./nim c -r --noMain --threads:on /e/prg/nim/my_code/test_nimx.nim says .nimble\pkgs\nimx-0.1\nimx\image.nim(594, 17) Error: undeclared field: 'statusCode'

the test_nimx.nim is just your demo

# File: main.nim
import nimx.window
import nimx.text_field
import nimx.system_logger # Required because of Nim bug (#4433)

proc startApp() =
    # First create a window. Window is the root of view hierarchy.
    var wnd = newWindow(newRect(40, 40, 800, 600))

    # Create a static text field and add it to view hierarchy
    let label = newLabel(newRect(20, 20, 150, 20))
    label.text = "Hello, world!"
    wnd.addSubview(label)

# Run the app
runApplication:
    startApp()

Please add

/usr/share/fonts/truetype

in font.nim abt line 351

this is the openSuse default truetype path

Is there one yet? I couldn't find one.

Would it be best to use a table in the meantime?

nimx/private/font/stb_ttf_glyph_provider.nim has a lot of references to stbtt* which it neither imports nor defines and which naturally block successful compilation. Those symbols seem to come from some c2nim + much manual work on Sean Barrett's stb_truetype.h. [ I made a brief attempt post c2nim, but it seems like a lot of manual work. ]

Hi, I just installed nimx via nimble on Ubuntu 16.04 and tried to run the example from the Readme with nim devel, but get the following error:

In the main example in the README, the first import fails because GL_VIEWPORT can't be found. Changing this to its value directly (2978) works. Not sure if the error is here or in the opengl package.
Using win8.1 x64, btw.

I get an error when compiling the any code sample with nimx:
stack trace: (most recent call last) nimx/resource_cache.nim(140) getResourceNames nimx/resource_cache.nim(128) getEnvCt lib/pure/strutils.nim(2242) removeSuffix lib/pure/strutils.nim(2242, 9) Error: index out of bounds

This problem disappears when I use
$ export NIMX_RES_PATH="123"

Would be nice for newbies not to have to build their own menubar each time they want a standard "windows" with the usual File|Edit|....|Help menu bar across the top (or whichever side)

Getting this error on Linux Mint 18 while trying to compile the simple example given below:

import nimx.window
import nimx.text_field
import nimx.system_logger # Required because of Nim bug (#4433)

proc startApp() =
    # First create a window. Window is the root of view hierarchy.
    var wnd = newWindow(newRect(40, 40, 800, 600))

    # Create a static text field and add it to view hierarchy
    let label = newLabel(newRect(20, 20, 150, 20))
    label.text = "Hello, world!"
    wnd.addSubview(label)

runApplication:
    startApp()

To be clear: I am using Nim version 0.17.0

Running on Ubuntu 16.04.2 (to be accurate, it's an Ubuntu fork called elementaryOS), nim 0.17.0 (2017-05-17).

Trying to compile an example from the README:
nim c -r --noMain --threads:on main.nim

What I get after the compilation:

could not load: libSDL2.so
compile with -d:nimDebugDlOpen for more information
Error: execution of an external program failed: '/home/vladyio/projects/nim/Tutz/tutzui/main '

Running with -d:nimDebugDlOpen prints out just libSDL2.so: cannot open shared object file: No such file or directory

As far as I understand I have libSDL installed on my system since ls /usr/lib/x86_64-linux-gnu/ | grep libSD gives the following:

libSDL-1.2.so.0
libSDL-1.2.so.0.11.4
libSDL2-2.0.so.0
libSDL2-2.0.so.0.4.0
libSDL.a
libSDL_image-1.2.so.0
libSDL_image-1.2.so.0.8.4
libSDLmain.a
libSDL_mixer-1.2.so.0
libSDL_mixer-1.2.so.0.12.0
libSDL.so

Maybe I have to set up some symlinks for the library or anything else? Where must I put the libSDL file?

TL;DR: please add the BSD license file.

There is no license file for this project. The nimble metadata says "BSD", which would have been sufficient for a license that doesn't have vastly different variants, but there's ambiguity if you mean BSD2, BSD3, or the horribly restrictive BSD4. I personally use the Unlicense for all my works, but any license on the copyfree.org white-list would also be OK.

I am promoting Nim as, among its many other virtues, a programming language with the most no-hassle unencumbered no-lawyers-needed permissively-licensed ecosystem. 89% of nimble packages fit the copyfree.org definition of free software, compared for example to 81% to runner-up cabal or 64% for npm. Towards this end, it is important to resolve any ambiguities in the licensing.

Thank you very much for all your great contributions to the Nim ecosystem! 👍

I followed the instructions but when I compiled/ran the example I get:

Hi!
I've read through a bunch of the other issues (there seems to be a lot, comparatively ) regarding the example code in the readme. Would it not be good if we had a bunch of troubleshooting tips?
Like:
If your having trouble installing nimx, try doing the following before posting an issue:
nimble install -y variant
nimble install -y https://github.com/yglukhov/ttf
nimble install nimsl

I compile your "main" example In windows 10,
Error info:
c:\users\allen.nimble\pkgs\nimx-0.1\nimx\portable_gl.nim(227, 52) Error: undeclared identifier: 'unsafeAddr'

Is this being worked on? I managed to figure out the place to start is probably to make a GraphicsContext from context.nim, other than that there is little go off of from there.

nimx_pasteboard_x11.c:(.text+0xf8d): undefined reference to `SDL_GetWindowWMInfo'

Error occurred when running the sample code in README. Test runs without problems.

Please add the "curLoop" as public property.

I'm having some build problems, which may be due to my using 0.15 on Windows which I think has various issues. Anyway, first I hit that in ttf it couldn't find memory.h - and it doesn't seem to be in the mingw distributed with nim 0.15 - so I copied it from another mingw installation.

But then...

nim c --threads:on -r sample01_welcome.nim

gives

c:\users\alynch.nimble\pkgs\nimx-0.1\nimx\view_event_handling.nim(14, 8) Error: method is not a base

any hints?

import nimx.window,
       nimx.text_field,
       nimx.scroll_view,
       nimx.system_logger,
       strutils

runApplication:
    let wnd = newWindow newRect(40, 40, 640, 480)
    let tv = TextField.new newRect(40, 40, 100, 100)
    tv.resizingMask = "wh"
    tv.text = "abcdefgi\n".repeat(20)
    tv.multiline = true
    let scroll = newScrollView tv
    wnd.addSubView scroll

The scrollbars are incorrect initially. It appears correct after I select some text, minimize the window and then bring up the window. Is my code correct?

When I follow these instructions:
cd $(nimble path nimx)/test
nake # Build and run on the current platform

I get a permission denied error. I changed the permissions on the test/nakefile, and now I get this error, and it just hangs, and I have to kill the terminal session from the system monitor:

I'm on elementary OS 0.3.2 Freya (64-bit), Built on Ubuntu 14.04

Any plans for static linking?

Hello,

new to nim and nimx. setting up my environment (debian amd64). Compilation of your hello world on linux for linux works OK, but when trying to cross compile for WIN target:

nim --os:windows --cpu:amd64 --gcc.exe:x86_64-w64-mingw32-gcc --gcc.linkerexe:x86_64-w64-mingw32-gcc --app:gui -r --noMain --threads:on c main.nim

it fails (probably during linking) with this message:

/usr/lib/gcc/x86_64-w64-mingw32/6.3-win32/../../../../x86_64-w64-mingw32/lib/libmingw32.a(lib64_libmingw32_a-crt0_c.o): In function main': ./mingw-w64-crt/crt/crt0_c.c:18: undefined reference to WinMain'
collect2: error: ld returned 1 exit status

Full log here: https://pastebin.com/UwfB8D4J

Or do i need to cross-compile libsdl2 first?

thank you

Each mouse wheel event scrolls much less than the default font height, so scrolling this way is impractical at the moment.

hi @yglukhov
I get this error when build main.nim, can you please take a look?
I have nake and nimx installed successfully by nimble.

by the way, when I tried to build examples in test folder, I get a lot of below errors:

Note: I am using Nim 0.14.2 binary.

How can we get rid of these system readouts? I'm not seeing it.

It should not be possible to setup TextField with a rect that is smaller than text inside it.

I get:

main seems to be defined in both nimx/linkage_details.nim and main.nim.

Run this:

And try to click on tabs(Welcome, Controls, Image, Animation) not in order.
I cannot activate tab the first time.

Also font on the "segmented control" is very blurred.
If I press buttons on the "segmented control" I get text outside of text field.

I use Ubuntu 14.04 x64 with devel branch of nim.

When compiling the example, I get an error on ttf_ttf.c, saying that it cannot find memory.h.

ttf_ttf.c:701:23: fatal error: memory.h: No such file or directory.
#include <memory.h>

Is there any solution to this? Or a memory.h file that I need to just copy and paste into the nimcache directory?

File: main.nim

import nimx.sdl_window
import nimx.text_field

First create a window. Window is the root of view hierarchy.

Currently there are two types of windows. SdlWindow should be used

with native targets, JSCanvasWindow should be used for WebGL target

var wnd : SdlWindow
wnd.new()
wnd.init(newRect(40, 40, 800, 600))

Create a static text field and add it to view hierarchy

let label = newLabel(newRect(20, 20, 150, 20))
label.text = "Hello, world!"
wnd.addSubview(label)

Run the main loop

runUntilQuit()

I run this:
nim c -r --noMain main.nim

And get this:
/home/nick/.nimble/pkgs/nimx-0.1/nimx/sdl_window.nim(78, 87) Error: undeclared identifier: 'SDL_WINDOW_ALLOW_HIGHDPI'

Hi @yglukhov
There are some texts on the upper right corner of the demo GUI:
FPS:xx
DIPs:xx
Timers:xx
Images:xx
...

Is it possible to remove them? I want a clean GUI.

Thanks,
Yingjun

Here's a short example that can be used to reproduce the issue:

import nimx.window
import nimx.text_field
import nimx.system_logger
proc startApp() = newWindow(newRect(40, 40, 800, 600)).addSubview(newTextField(newRect(20, 40, 20, 20)))
runApplication: startApp()

The crash occurs when the first character entered into the field is '€' for example, but it only results in a delay when it is not the first character. Characters like 'å', 'ä', and 'ö' do not cause a crash, but they also result in a delay of about 2 seconds.

Here is the stack trace for when it crashes:

In windows 10
nimx can not support unicode character, such as chinese character

If indeed it's not possible, then some ways to deal with this includes:

• Allowing the engine to be updated without exposing implementation details of targets, thus allowing timers to be bypassed
• Associating an object with a timer, that is passed to the callback, or turning the callbacks into closures
