In a similar way could you allow the use of showNormal or showMinimzed rather then showMaximized

populating ControlList takes veeeryyyy loooong time

As populating a ControlList with a few thousands of lines, each with a few columns (it works the same with single columns), my UI hangs for some long minutes before getting responsive again.

Here is sample code to reproduce

my_list.value = [[x] for x in range(5000) ]

By Reading QT forums, I went on the following topic about performance issues with QTableWidget.
https://bugreports.qt.io/browse/QTBUG-57848

Is it possible to disable resizecolumn by default instead of enabling it ?
Or at least, use QT's ResizeToContents only upon content insertion complete when mass replacing value ?

Window starts maximized

Ubuntu 16.04

Is there a way to block them from maximizing?

function 'FT_New_Face' not found

Source of issue

After installing via pip install pyforms-gui (installation was succesfull, no errors across all dependencies) and running example project, I have error:

Traceback (most recent call last):

This seems like some low-level dll stuff that I don't understrand, and was unable to find solution.

How to style window

I am able to style the MainWindow. How do I style a Window that has BaseWidget as Constructor?

OpenCV version issue

There is an issue if the user has installed a different version of opencv-python than 3.4.5.20 (same error with pip). The only workaround I've found so far is to modify line 45 from 'opencv-python==3.4.5.20', to 'opencv-python>=3.4.5.20', from setup.py.

ControlNumber can't set negative value

Use QListWidgetItem instead of QTableWidgetItem for ControlList

QTableWidgetItem doesn't provide any method to help with an eventual search function, notably the QtWidgets.QListWidgetItem.setHidden method from QListWidgetItem.

The lack of hiding feature for the different items populating a list makes it hard to implement any kind of filtering system. If you know of a way to hide the table elements based on a string, please do tell me.

Can't seem to get the mainmenu to show for MacOS

I'm just running the SimpleExample5 and I don't see the mainmenu option show . See attached screenshot.

Python version 3.7.4

Though upon install the lib, using pip install PyForms-GUI, the installation failed.

ControlFilesTree - how to get selected file?

Is there a way to know which file is selected?

opencv-python==3.4.5.0 could not be installed

Hi,
At the setup.py, opencv-python==3.4.5.0 was set, but it could not be installed as it is not exist on the its pypi.
I have tried git clone and update the setup.py to not specify opencv-python version.
It looks fine. Is there any way to avoid this info msg.

Could you please check this case when you are available ?
Thanks.

how to control size of main window

it always starts at the max size of window

how to application icon?

How do you set the application icon? setWindowIcon does not seem to do anything

ControlDir doesn't have correct label

I have been using ControlFile with success, but it doesn't seem that pyforms has an option to request a folder instead of a file.

I guess this is a feature request, rather than an issue, but I don't know where else to file it.

ControlImage example

I am unable to run the ControlsImage example in pyforms-gui-4\tutorials\Controls4Docs.
The GUI opens but once the open button is pressed the GUI crashes.
Here is the error that I receive:

Traceback (most recent call last):
File "ControlImage.py", line 31, in __open
self._control.value = '/home/ricardo/Desktop/lena_color.png'
File "C:\ProgramData\Anaconda3\lib\site-packages\pyforms_gui\controls\control_image.py", line 73, in value
self._imageWidget.paint([value])
File "C:\ProgramData\Anaconda3\lib\site-packages\pyforms_gui\controls\control_player\AbstractGLWidget.py", line 328, in paint
self.imgHeight, self.imgWidth = frames[0].shape[:2]
AttributeError: 'str' object has no attribute 'shape'

Not getting the complete file path when using the ControlFile widget to save a file

Source of issue

When using the ControlFile widget, the call to the underlying Qt method to get a file path is correct but here:

pyforms-gui/pyforms_gui/controls/control_file.py

Line 51 in 0f6cd96

value = value[0]

only the first character of the path is kept. This is because when using the same widget to open a file, a more generic call is made (to be Qt4 and Qt5 compatible I guess) and it is possible to get back a tuple and not just a string.

Potential solution

Possible solutions to this issue could be:

• Test the type of the value and treat differently tuples and strings
• Check if one is using the widget for opening or saving

Is there an updated doc on how to import CSS Styles?

I am trying to organize a bunch of text fields to look similar to the standard way how address forms are formatted. But I can't seem to find a way to import the css styles.

The examples use the master branch, but I am using v4.

Pyforms Tutorial Missing "AddMenuFuntionality"

Hi,

I am just wondering how you made the "AddMenuFuntionality" file, it wasn't mentioned to be made in the tutorial as I am trying to learn and will apply this to my own application afterwards... Just wanted to see the end result, but I get errors because it is missing. Do you have the code for this the "AddMenuFuntionality" file?

Thanks so much! Pyforms is great!
