modern tkinter kütüphaneleri

• customtkinter
• ttkbootstrap

widget’ların (bileşen) konumlandırması için 3 tane yerleşim yöneticisi var: pack, grid ve place

• grid: satır ve sütunlardan oluşan bir ızgara üzerinde düzenler (tablo gibi).
• pack: Widget’ları yatay/dikey bloklar halinde sıralar
• place: Widget’ları koordinatlara yerleştirir.

Aynı seviyede tek türk yerleşim yöntemi kullanılır. iç içe yerleşimlerde farklı yöntemler kullanılabilir.

Pack

• side: top, bottom, left, right
• fill: x, y, both
• expand: True, False
• anchor: n,s,w,e,ne,nw,se,sw
• padx, pady: sayısal değer, padx=5 veya padx=(4,6) gibi kullanılabilir.

Grid

• row: satir tamsayı
• column: sütun tamsayı
• rowspan: kaç satır tamsayı
• columnspan: kaç sütun tmsayı
• sticky: n,s,e,w, ve bunların 2’li, 3lü, 4lü kombinasyonu.

• padx, padx: sayısal değer, padx=5 veya padx=(4,6) gibi

• weight: columnconfigure(0, weight=1), rowconfigure(1, weight=2) gibi kullanılır.

Place

• x, y
• relx, rely

Veri türleri

• StringVar()
• IntVar()
• DoubleVar()
• BooleanVar()

get() ve set() ile veri alınabilir ve set edilebilir.
Örnek:

name_var = tb.StringVar(value="my name")
entered_name = name_var.get()

age_var = tb.IntVar()
age_var.set(25)

Temel widget’lar

• Frame: çerçeve
• Label: etiket
• Button
• Entry: metin/girdi kutusu
