Description:: Returns the Y of the top border of the screen, which is also a distance in screen measurement units from top left corner of the default viewport (0,0) of the screen to the top border of the screen. Since it is going in opposite way of the Y axis, the value is negative. The measurement units depend on the current screen resolution getResolution. See also SafeZone.
Groups:: GUI Control - Positioning

Example 1:: _screenTopBorderY = safeZoneY; // returns a float value < 0
Example 2:: Create control 50% wide, 30% tall, centered on screen: private _ctrl = findDisplay 46 createDisplay "RscDisplayEmpty" ctrlCreate ["RscText", -1]; _ctrl ctrlSetBackgroundColor [1,0,0,0.5]; private _ctrlWidth = 0.5 * safeZoneW; // 50% of screen width private _ctrlHeight = 0.3 * safeZoneH; // 30% of screen height _ctrl ctrlSetPositionW _ctrlWidth; _ctrl ctrlSetPositionH _ctrlHeight; _ctrl ctrlSetPositionX ((safeZoneW - _ctrlWidth) / 2 + safeZoneX); // center it horizontally _ctrl ctrlSetPositionY ((safeZoneH - _ctrlHeight) / 2 + safeZoneY); // center it vertically _ctrl ctrlCommit 0;
