Cara mengubah kecepatan gulir roda mouse per aplikasi

Apakah mungkin untuk memiliki kecepatan gulir roda mouse yang berbeda berdasarkan aplikasi yang berjalan di atas (fokus).

Seperti kecepatan gulir yang lebih lambat untuk guake agar mudah dibaca dan lebih tinggi untuk peramban web gulir lebih cepat.

pengantar

Script berikut dynamic_mouse_speed.py memungkinkan menentukan berapa penunjuk mouse dan / atau kecepatan gulir seharusnya ketika jendela yang ditentukan pengguna memiliki fokus.

Penting : skrip membutuhkan imwheelprogram untuk meningkatkan kecepatan gulir. Silakan instal melaluisudo apt-get install imwheel

Pemakaian

Seperti yang ditunjukkan oleh -hbendera:

usage: dynamic_mouse_speed.py [-h] [-q] [-p POINTER] [-s SCROLL] [-v]

Sets mouse pointer and scroll speed per window

optional arguments:
  -h, --help            show this help message and exit
  -q, --quiet           Blocks GUI dialogs.
  -p POINTER, --pointer POINTER
                        mouse pointer speed,floating point number from -1 to 1
  -s SCROLL, --scroll SCROLL
                        mouse scroll speed,integer value , -10 to 10
                        recommended
  -v, --verbose         prints debugging information on command line

Skrip memungkinkan pengguna untuk memilih jendela yang ingin mereka lacak dengan klik mouse. Pointer mouse akan berubah menjadi silang dan pengguna dapat memilih jendela yang mereka inginkan.

Menjalankan python3 dynamic_mouse_speed.pysendiri hanya menampilkan dialog sembulan dan tidak melakukan apa pun dengan sendirinya.

Menjalankan python3 dynamic_mouse_speed.py -s 5meningkatkan kecepatan gulir, sementara python3 dynamic_mouse_speed.py -s -5memperlambat kecepatan gulir ke bawah. python3 dynamic_mouse_speed.py -p -0.9mengurangi kecepatan pointer, sementara python3 dynamic_mouse_speed.py -p 0.9meningkatkan kecepatan pointer. -sdan -popsi bisa dicampur. -vmenghasilkan informasi debug pada baris perintah.

Catatan

• beberapa contoh skrip memungkinkan pengaturan kecepatan per setiap jendela terpisah.
• Saat menjalankan dari baris perintah, dialog sembulan menghasilkan pesan berikut: Gtk-Message: GtkDialog mapped without a transient parent. This is discouraged.Ini dapat diabaikan.
• Konsultasikan Bagaimana saya bisa mengedit / membuat item peluncur baru di Unity dengan tangan? untuk membuat peluncur atau pintasan desktop untuk skrip ini, jika Anda ingin meluncurkannya dengan klik dua kali
• Untuk menautkan skrip ini ke pintasan keyboard agar mudah diakses, bacalah Cara menambahkan pintasan keyboard?
• Disarankan untuk menggunakan hanya satu mouse saat skrip berjalan, karena skrip ini beroperasi pada perangkat pertama yang diketahui memiliki Evdev Scrolling Distanceproperti
• Beberapa instance dapat mulai mengontrol beberapa windows, tetapi tidak disarankan untuk kinerja
