الاخوة الاعضاء فى منتدى الجرافيكس
اقوم الان بتصميم Frame كل البرامج التى
اكتبها ب Direct3D9.0 لكن وا جهتنى مشكلة
واحدة, هى ان عند تصغير النافذة تقوم بتعليق
الجهاز. ارفق لكم الملف.

}السلام عليكم ,,
نأسف على التأخير ,,
المشكلة أن حلقة الرسائل عندما لايكون هناك أي حدث في صف الرسائل ,, تستدعى الدالة AppLoop() ,, ليعمل البرنامج ,, والمشكلة أنه اذا لم يكن هناك دالة في بلوك ال else في كما في الكود التالي ,, سيعلق البرنامج ,,
if( PeekMessage( &msg, NULL, 0U, 0U, PM_REMOVE ) )
{
TranslateMessage( &msg );
DispatchMessage( &msg );
}
else
{
}كودك المكتوب كالتالي :
if( PeekMessage( &msg, NULL, 0U, 0U, PM_REMOVE ) )
{
TranslateMessage( &msg );
DispatchMessage( &msg );
}
else
{
AppLoop();
}حيث أن بلوك ال else فيه استدعاء لتنفيذ ال AppLoop ,, وعند تصغير البرنامج فان الدالة AppLoop لن تفعل شيئا في الواقع لأنه لاتوجد مساحة للعرض كما فهمت أنا ولم أتعمق في الكود أصلا ,,
لكن يكفي أن تسكت البرنامج وقت تصغير البرنامج لكي لايفعل شيئا ويعود ليعمل فور تكبير النافذة مباشرة ,, لأنه في الواقع لايفعل شيئا حقا عند تصغير النافذة فكتبت الكود التالي في بلوك ال else :
if( PeekMessage( &msg, NULL, 0U, 0U, PM_REMOVE ) )
{
TranslateMessage( &msg );
DispatchMessage( &msg );
}
else
{
if(!minimized)
AppLoop();
else Sleep(10);
}حيث المتغير minimized يصبح true عند تصغير البرنامج ثم يصبح false عندما يعود للوضع الطبيعي مرة أخرى ,,
خذ الكود النهائي :
