摘要： A digitizer eraser system and method are provided so as to include a writing/erasing digitizer pen, a tablet, and a tablet driver for use in conjunction with a computer and corresponding display screen. The user selects and deletes text or cells with one stylus stroke. In one motion, the user presses select, moves the erasing stylus across the material to be selected, then at the end of the selection lifts the stylus off the tablet to delete or erase the selected material. The system permits erasing of text or objects from the display screen via a keystroke function only when predetermined cursor shapes are being used on the screen. The keystroke function is chosen from a group of possible erasing keystrokes, with the selected keystroke being based upon the cursor shape being used so that undesirable erasing keystrokes are not used in certain situations. Additionally, the cursor shapes displayed on the screen are changed in accordance with whether the stylus is in a writing or an erasing mode or position. In certain PC-based embodiments where the operating system is window-based, subclassing is used so that selection and erasure by the stylus is only permitted in subclassed windows, not all windows being subclassed.

摘要翻译： 提供数字化仪橡皮擦系统和方法，以便包括与计算机和对应的显示屏一起使用的写入/擦除数字化笔，平板电脑和平板电脑驱动程序。 用户选择和删除文字或单元格一个笔触笔。 在一个动作中，用户按下选择，将擦除的触控笔移动到要选择的材料上，然后在选择结束时将触控笔从平板电脑上取下来删除或删除所选材料。 只有当屏幕上使用了预定的光标形状时，该系统才允许通过击键功能从显示屏幕擦除文本或对象。 击键功能是从一组可能的擦除击键中选择的，所选择的击键是基于所使用的光标形状，使得在某些情况下不使用不期望的擦除键击。 此外，根据触笔是处于写入还是擦除模式或位置，显示在屏幕上的光标形状被改变。 在操作系统是基于窗口的某些基于PC的实施例中，使用子类化，使得仅在子类窗口中允许由触控笔的选择和擦除，而不是所有窗口都被子类化。
