I think it would be good to have a constructor that accepts a list. So we can get a working combobox without dealing with a lot of append
calls. What do you think about that? @joaoventura @superzazu
I keep getting the following error after building. Any recommendations on how I can fix this?

I've followed the instructions on building libui
and pylibui
in the README
.
I have problems about running tests and examples. Some of them ends with a segmentation fault. I think there are some problems about getters of components like window and checkbox. And I think it's about boolean difference between Python and C.
I'm using Ubuntu 16.04
Am I the only person that have problems about tests or anyone can confirm that there is a problem?
Really sorry for being a noob here but I keep getting an error when trying to run a pylibui sample application. I set it up by doing the following on my Windows 10 64-bit machine.
However, my programs fail to run and I get the following error:

Any help?
Hi ๐
This is my first visit to this fine repo, but it seems you have been working hard to keep all dependencies updated so far.
Once you have closed this issue, I'll create separate pull requests for every update as soon as I find one.
That's it for now!
Happy merging! ๐ค
We need someone to implement editable comboboxes.
Please feel free to ask for help, if you want to work on this.
The script to generate automatically the bindings parses the libui header file in pylibui/scripts/ui.h. The current header file is 4 months old now, so there is definitely some things that were added to libui in the last months that are not in the pylibui ctype wrapper files.
We just need to regularly copy ui.h from the libui project, to keep binding generation up-to-date and manually integrate the new functions in the wrapper files. In the future we may try to automatize some things, but let the project mature a little bit more..
Hello,
As the pylibui
wrapper is supposed to be pythonic, I thought it would be great to use the properties instead of defining setValue
/getValue
-like methods.
Here is a little implementation example for checkboxes checked
attribute:
@property
def checked(self):
"""
Returns whether the checkbox is checked or not.
:return: bool
"""
return libui.uiCheckboxChecked(self.control)
@checked.setter
def checked(self, checked):
"""
Sets whether the checkbox is checked or not.
:param checked: bool
:return: None
"""
libui.uiCheckboxSetChecked(self.control, checked)
That way, that would allow us to do things like:
if my_checkbox.checked:
my_checkbox.checked = False
instead of...
if my_checkbox.getChecked():
my_checkbox.setChecked(False)
What do you think ? Should I make a PR for this ?
Have a good day,
Nicolas.
The window example does not work. After closing the window, the python process just keeps running. SIGINT is ignored. SIGQUIT terminates the process.
Jupyter Notebooks (can be installed with pip install jupyter notebook
and run with jupyter notebook
) has mainly data processing usage and such but is also tweaked to support pyqt and wxpython, I wonder, if it would possible to support libui on it also, steps to reproduce:
jupyter notebook
on pylibui folderExpected:
Everything goes smoothly and I could repeat running of the sample code
Actual:
Jupyter will not notice even the created window is closed or crashes.
I think things can be tweaked to work more smoothly, for example see this documentation, it seems IPython.lib.guisupport
provides good utilities to enhance the support.
We need someone to implement seperators.

Hi,
I can see that there is not any commit since more than one year.
Is pylibui
dead / call for maintainer ?
As I am using pylibui
, I can maintain it.

I want to use this for the menu of my game, and looking at the libui controlgallery screenshots they have something called a "Combobox". It looks like you havent implemented it yet though. Do you have any plans to do it? If not, id be willing to try and do it myself
EDIT: I tried doing it myself, but after generating the bindings, I had no idea how to use them or how to make a higher level wrapper around them. It would be great if you could add comboboxes yourself, as I cant figure it out
Followed your guide in the README and did the following:
sudo -H python3 setup.py install
When trying to run the example on the README, I would get this error:
Traceback (most recent call last):
File "pylibui-test.py", line 1, in <module>
from pylibui.core import App
File "/usr/local/lib/python3.5/dist-packages/pylibui/core.py", line 6, in <module>

self._handle = _dlopen(self._name, mode)
OSError: /usr/local/lib/python3.5/dist-packages/pylibui/libui/sharedlibs/libui.so: cannot open shared object file: No such file or directory
Fixed this by copying over the sharedlibs/
folder but then I got this error:
Traceback (most recent call last):
File "pylibui-test.py", line 2, in <module>
from pylibui.controls import Window
ImportError: No module named 'pylibui.controls'
This had me stumped until I realized that the entire controls/
folder was not copied during setup. Once I manually copied it over to the install location, then it worked fine.
If you can, please change your setup procedure to automatically take care of these steps to make installation of this library painless.
libui announced removal of some window functions. So our window implementation is a bit broken now.
Should we remove these functions?
I noticed we don't have a "label" example like we do for all the other widgets.
libui no longer uses cmake but meson
the readme should probably be updated accordingly
cheers!
I think we should start to write a documentation. What do you think? I'm not very good at writing in English ๐ but I can read and review
Also should we use a doc generator or do wiki pages suffice?
We need an example for tab, so we can better understand all methods' behaviours.
Check other examples for guidance, feel free to ask for help if you need.
Any ideas?
We need someone to implement groups.
Please feel free to ask for help, if you want to work on this.
There is an error about lineno variable in bindings.py
if start <= lineno + 1 <= end:
lines.append(line.strip())
First line must be if start <= lineno <= end:
. Because when lineno +1 used in the condition, the first item of the returned lines is going to be an empty string and bindings.py can not create the last function of sections. (i.e. uiNewSomething)
A screenshot of the lines returned by return_lines
function for combobox, see the first item
Some tests have a TODO line with a single raise statement, they are failing and should be removed.
In wrappers (i.e. the files under pylibui/libui
) there are some bool casts. We want wrappers to be really simple. So these casts should be moved to corresponding files in pylibui/controls
and docstrings must be corrected as well.
Correct files above and please review all wrappers. If they have unnecessary details that can be implemented in pylibui/controls
, fix them as well.
Feel free to ask for help if you need
Hello,

Original libui has a control gallery that looks really cool. It's like an example of all controls. I think we should add a control gallery to pylibui too. And we can improve it as we add new controls. What do you think?
... somehow i would have expected to be adding children with addChild
, not with setChild()
...
I followed the instructions on windows and when I run the example program I get the following error:
Traceback (most recent call last):
File ".\hello.py", line 8, in <module>
from pylibui import libui

OSError: [WinError 126] The specified module could not be found
Am I doing something wrong or is it a bug? The directory structure is as follows:
Ran on windows 8.1 with python 35 and the latest version of both libui and pylibui
EDIT: in init.py, changing this works
SHARED_LIBS = os.path.join(SHARED_LIBS_PATH, 'libui.dylib')
to
SHARED_LIBS = os.path.join(SHARED_LIBS_PATH, 'libui.dll')
There are some tests with a single raise keyword and a TODO comment. They are failing. I think they must be commented out until a way to simulate mouse press found or... what about removing them completely? Because I don't think we can find a way to simulate mouse press.
Instead of tests we can request working examples that uses the functions which need mouse input from contributors.
It's a bit difficult to change file content for every template/section. I offer to use sys.argv in bindings.py file so we can use it just like:
$ python3 bindings.py combobox
I can open a pull request soon if you confirm it.
