快板环境变量设置

_________________________________________________________________________________

类型:

显示/光标

全屏光标停滞处理:

全屏光标可能在三维显卡加速处理器上会有停滞问题.

设置解决全屏光标停滞问题

pcb_cursor:

设置快板显示的光标类型（默认为十字光标）.

全屏光标角度设置:

仅适用于全屏的光标（见pcb_cursor变量）。

默认情况下，显示的是无限的十字正交。

这个变量是指定全屏光标的角度（0~90）。

__________________________________________________________________________________

类型:

显示/提示快板预选和应用模式选择

自定义数据提示延迟时间:

默认情况下,数据提示定制消失250毫秒的光标离开之后的对象数据提示显示。

这是所需的时间用户移动光标到要访问的数据提示先进的功能。

这允许这种延迟是调整之间的0（即时数据提示消失）2000毫秒。

数据提示延迟:

默认情况下，数据提示出现如果光标停留在250毫秒的相同位置。

这允许延迟

要调整100和2000毫秒之间。

数据提示显示位置:

默认位置为下一个光标处.（如果设置了将会在工作面板的底部）

禁用数据提示:

禁用上下文敏感的数据提示，当鼠标悬停在快板的数据元素
