Visual C++ Forma muxitida ixtiyoriy dastur tuzish

TextBox komponentasi TtextBox sinfining to’g’ridan-to’g’ri hosilasi bo’lib, uning barcha xususiyatlari, metodlari va voqealariga vorislik qiladi.


Button

Yozuvli to’rtburchak tugmani yaratadi. Tugmacha bosilganda, dasturda biror-bir hatti-harakat nomlanadi (initstiallashtiriladi).

Tugmachalar ko’proq dialogli darchalarda qo’llanadi. Default xususiyatining true qiymati tomonidan tanlab olingan yashirin tugmacha, dialog darchasida har gal enter klavishasi bosilganda OnClick voqea qayta ishlatgichini ishga tushiradi. Cancel xususiyatining true qiymati tanlab olgan bekor qilish tugmachasi, dialog darchasida har gal Escape klavishasi bosilganda, OnClick voqea qayta ishlatgichini ishga tushiradi.
