# Utilities #
## Overview ##

A package for collecting utilities I usually use in my Qt-projects in Python.
Some modules depend on others but some can be used on their own. Some modules
might have stub files to assist development, but they always contain an
initializer function to create the necessary stub files if they are missing
when the module is first imported. The functionality of subclasses of QDialog
are also available as subclasses of QDockWidget (floating, same-window dialogs).
There are no set goals for this project other than having these things in one
place, in a structured manner.

The package can be used as follows:
```python
from utils_qt_mk.colours import ColourSelector
```

The simplest way to use editors (file dialog, message, theme) is to import and
run the _TestApplication class of the given module, all of which are subclasses
of QMainWindow.

## Contents ##
### _general ###

General functions, classes etc. for internal use in other parts of the package.
Modules usually depend on it.

### colours ###

Adds the [standard R colour palette](https://r-charts.com/colors/) to Qt applications. It provides a
singleton object named Colours, with attribute access to all the colours of R's
*colors()* function. These can be conveniently selected from a colour selector
dialog, either from a drop-down list (by name) or from a grid (by visual
selection). Based on this selector there is a colour scale creator dialog,
where from a number of selected colours and set number of steps a colour scale
can be defined for further use e.g. for plotting. It optionally uses **theme**:
if the module can be imported, the dialogs can have a theme.

### custom_file_dialog ###

Provides predefined file dialogs (PathTypes singleton) customized by a JSON file
and a creator dialog. In the latter, a custom dialog could be defined, setting
its type (source/destination), window title, dialog type (to open/save a file or
open an existing directory), extension filter and associated path. Another
function of these dialogs is to provide navigation history: if a path is
successfully selected, the JSON file gets updated with it.

### message ###

Provides predefined message boxes (MessageBoxType singleton) that can have a
theme assigned (so it depends on **theme**) and a creator dialog. In the latter,
a custom message box can be defined, setting its category (e.g. warning),
window title and message (text content of the message box). A 'custom' category
message box can also have its icon, buttons and flags set.

### progress_dialog ###

Provides a cancellable, optionally nested progress dialog, reporting on a
compatible process ran by a QObject-subclass on a separate thread. It also has a
(package private) example of a compatible worker object. It optionally uses
**theme**: if the module can be imported, it can use the preset themes.

### theme ###

Provides a simple way to apply a predefined theme to Qt-widgets. It also adds a
singleton object named WidgetTheme that has attribute access to all the defined
themes. The *set_widget_theme()* function uses this singleton to select a theme.

### theme_creator ###

Depends on **theme** and **colours** to provide a theme creator dialog. It
provides a simple interface to edit and preview existing themes or to create new
ones.
