My problem was: how to set size of (set Scale9) button or Sprite.
My version of solution:Image may be NSFW.
Clik here to view.
float S_sz = 513; // set it or get it - Sprite real size, in pixels (in my case - 513x513 pixels); float B_w = S_sz / 3.0f; // -the width of "border" == size of Sprite block in pixels; since Sprite will be divided to 3x3 blocks, so we have to divide Sprite size by 3; Size block_q = Size(3.5, 4); // size of the Spite on screen - in block units! (in my case - 3.5x4 blocks); // should be more than 2x2 if you want border corners to be squared. Scale9Sprite * p_sp = Scale9Sprite::create("sprite_file_name.png"); if (p_sp) { p_sp->setScale9Enabled(1); this->addChild(p_sp, 100); // todo Z order!! p_sp-> // here we set Scale9 button or Sprite size in blocks; setPreferredSize // setContentSize // both works ok; (Size( B_w * block_q.width , B_w * block_q.height )); auto object_size_on_screen_on_pixels = Size( 123, 456 ); // todo - by yourself; float scale = object_size_on_screen_on_pixels.width / ( B_w * block_q.width); p_sp->setScale( scale ); // here we set Scale9 button or Sprite size in pixels - on screen; }
