ORACLE Form 鼠標形態 CURSOR_STYLE

Oracle Forms Builder中，常會出現等待後臺調用pck或者等待請求運行的情形。

等待過程當中，爲了更友善地展示當前狀態，防止用戶方誤操做，常會使用變動鼠標形態的方式。

oracle form內置函數 SET_APPLICATION_PROPERTY 的 CURSOR_STYLE 屬性能夠實現這一功能。

SET_APPLICATION_PROPERTY(CURSOR_STYLE, 'BUSY'); --忙碌狀態
SET_APPLICATION_PROPERTY(CURSOR_STYLE, 'DEFAULT'); --普通狀態

好比，WIN Aero鼠標方案，忙碌狀態爲有個轉動的圓圈。
