pyqt-custom-titlebar-setter

PyQt custom titlebar setter.

This is movable/resizable.

When resizing, cursor shape will be automatically changed depends on the direction of edge where the cursor is hovering over.

For example, you want to resize the window horizontally, cursor shape will be changed like "⇿".

You can set the title, and icon which should be SVG type.

You can set the min/max/close buttons separately.

This package supports full-screen. If your app has full screen, this custom titlebar can perfectly deal with it. So there's no need to do another chore for full-screen.

This also makes the application's font look better by setting the font family to 'Arial'(which looks modern and commonly used), antialiasing.

The range of font size is set to 12~30 which is not too big, not too small.

Requirements

• PyQt5 >= 5.15 - This package is using startSystemMove, startSystemResize which were both introduced in Qt 5.15.

Setup

python -m pip install pyqt-custom-titlebar-setter

Included Packages

• pyqt-custom-titlebar-window

Usage

CustomTitlebarSetter.getCustomTitleBarWindow(main_window: QWidget, 
                                             title: str = '', 
                                             icon_filename: str = '',
                                             font: QFont = QFont('Arial', 14), 
                                             hint: list = ['min', 'max', 'close'],
                                             align=Qt.AlignCenter, 
                                             bottom_separator: bool = False
                                             ) -> CustomTitlebarWindow

• main_window is your widget.
• title is windows title. If you set this by default (empty string), title is based of the title you set with setWindowTitle.
• icon_filename is title bar's icon. Icon file should be svg file. If it is not set, then there is no icon.
• font is font of the title. Font size should be at least 14.
• hint is hint of the button on the title bar. For example, if you give the value such as ['min', 'close'], the title bar buttons will contain minimize and close buttons only.
• align is alignment of the title. You can give Qt.AlignLeft, Qt.AlignCenter, Qt.AlignRight. Some of these are not recommended depending on the title bar button's position.
• bottom_separator decides whether you want to put the separator(horizontal line) at the bottom of the title bar. If it is set to True, line will be shown between title bar and main widget.

Example

0. Simple way for people who clone this package

test.py is included in package just for people who cloned this for testing.

python test.py

1. Very basic text editor

Code Sample

from PyQt5.QtWidgets import QApplication, QWidget, QGridLayout, QTextEdit
from pyqt_custom_titlebar_setter import CustomTitlebarSetter


class TextEditor(QWidget):
    def __init__(self):
        super().__init__()
        self.__initUi()

    def __initUi(self):
        self.setWindowTitle('Text Editor')
        lay = QGridLayout()
        lay.addWidget(QTextEdit())
        self.setLayout(lay)


if __name__ == "__main__":
    import sys

    app = QApplication(sys.argv)
    widget = TextEditor()
    window = CustomTitlebarSetter.getCustomTitleBarWindow(main_window=widget, icon_filename='dark-notepad.svg')
    window.show()
    sys.exit(app.exec_())

Result

How about dark theme?

If you want to set dark theme, install the pyqt-style-setter, then write code like this.

...
widget = TextEditor()
StyleSetter.setWindowStyle(widget, theme='dark') # write it at this spot, BEFORE calling getCustomTitleBarWindow.
window = CustomTitlebarSetter.getCustomTitleBarWindow(main_window=widget, icon_filename='dark-notepad.svg')
...

By the way, you can clearly see the title label and min/max/close button color changed based on background's color automatically.

Now let's apply this to some of the applications.

※ From now on, examples below are using dark theme. Of course, you don't have to use this.

2. pyqt-dark-notepad - DarkNotepadApp class

Code Sample

from PyQt5.QtWidgets import QApplication
from pyqt_dark_gray_theme.darkGrayTheme import *
from pyqt_dark_notepad import DarkNotepad

class DarkNotepadApp(QApplication):
    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
        mainWindow = DarkNotepad()
        StyleSetter.setWindowStyle(mainWindow, theme='dark')  # you don't need this. this is just for adding style.
        self.__titleBarWindow = CustomTitlebarSetter.getCustomTitleBarWindow(mainWindow,
                                                                             icon_filename='ico/dark-notepad.svg')
        self.__titleBarWindow.show()
