NotifyIcon klassi
Quyidagi NatifyIcon klassidan foydalanish keltirilgan Unda Chiqish bandiga ega ContextMenu NotifyIcon.ContextMenu xususiyatiga tayinlangan boʻlib, u foydalanuvchiga ilovani yopish imkonini beradi. DoubleClick voqea sodir boʻlganda, ariza shakli Form.Activate usulini chaqirish orqali faollashtiriladi.

Bildirishnoma sohasidagi piktogrammalar virusdan himoya qilish dasturi yoki ovoz balandligini boshqarish kabi kompyuter fonida ishlayotgan jarayonlarga yorliqlardir. Ushbu jarayonlar o'zlarining foydalanuvchi interfeyslari bilan ta'minlanmaydi. NotifyIcon sinfi ushbu funksiyada dasturlash usulini taqdim etadi. Icon xususiyati bildirishnoma sohasida paydo bo‘ladigan belgini belgilaydi. Belgi uchun qalqib chiquvchi menyular ContextMenu xususiyati bilan bog‘lanadi. Matn xususiyati Asboblar uchun maslahat matnini tayinlaydi. Belgining bildirishnomalar sohasida paydo boʻlishi uchun Visible xususiyati true ga oʻrnatilishi kerak.NotifyIcon komponenti Windows Forms ilovasiga tizim tepsisi bildirishnoma funksiyalarini qo'shish uchun ishlatiladi. Ilova ishga tushirilganda, tizim tepsisiga belgi qo'shiladi va biz ba'zi amallarni bajarish uchun belgiga ikki marta bosish yoki menyu qo'shishimiz mumkin.
Visual Studio 2010 yordamida Windows Forms ilovasida NotifyIcon yordamida dastur uchun tizim tepsisi belgisini qanday qo'shishni ko'rib chiqamiz.
NotifyIcon boshqaruvi vizual tasvirga ega emas va fonda komponent sifatida ishlaydi. NotifyIcon yaratish uchun biz NotifyIcon sinfidan yoki Form dizayneridan foydalanishimiz mumkin. Windows Forms ilovasiga NotifyIcon qo'shish uchun NotifyIcon komponentini asboblar qutisiga shaklga tortamiz.
NotifyIcon-ni qo'shgandan so'ng, siz qilmoqchi bo'lgan birinchi narsa piktogramma tepsisida ko'rsatiladigan Belgini qo'shishdir. Buni NotifyIcon-dagi kichik tutqichni bosish va 1-rasmda ko'rsatilganidek, Belgini tanlash havolasini tanlash orqali amalga oshirishimiz mumkin.


1-rasm.

NotifyIcon hodisalari

Oddiy stsenariyda biz ilova foydalanuvchi interfeysini ochish uchun Belgini ikki marta bosing va kontekst menyusini ochish uchun belgini o'ng tugmasini bosing. 2-rasmda NotifyIcon bilan bog'liq hodisalar ko'rsatilgan va biz DoubleClick voqea ishlovchisini o'rnatamiz va ikki marta bosish orqali dasturni ochamiz.
2-rasm.


3-rasm.
Davom etishdan oldin, tizim tepsisi belgisida sichqonchaning o'ng tugmasi bosilganda ochiladigan ContextMenuStrip boshqaruvi yordamida ContextMenu qo'shamiz. ContextMenu 3-rasmda ko'rsatilgan.
Quyida sanab o'tilgan ContextMenu elementining hodisa ishlovchilari uchun kod Bajarish menyusi bandida edi; biz dasturni faollashtiramiz va Yopish menyusi bandida biz dasturdan chiqamiz.
privatevoid executeToolStripMenuItem_Click(object sender, EventArgs e) {
this.Activate();
}
privatevoid closeToolStripMenuItem_Click(object sender, EventArgs e) {
this.Close();
}
Kontekst menyusini sozlash.Endi biz NotifyIcon kontekst menyusini o'rnatish uchun formani ishga tushirishga quyidagi kodni qo'shamiz.
notifyIcon1.ContextMenuStrip = contextMenuStrip1;
Mana sichqonchani ikki marta bosish hodisasi ishlov beruvchisi, bu yerda biz shunchaki Windowni faollashtiramiz.
privatevoid notifyIcon1_MouseDoubleClick(object sender, MouseEventArgs e)
{
if (this.WindowState == FormWindowState.Minimized) this.WindowState = FormWindowState.Normal;
this.Activate();
}
