OnScreenKeyboard - Little keyboard on the screen when no real keyboard is available

Description

Assume you want to run Oberon on a FPGA where you can attach a mouse or pointing device, but no keyboard. It should still be possible to toy with the system, until you find a way to add a keyboard.

In theory, no keyboard is needed, since you can always use interclicks to copy individual letters from a text file. But there are places (e.g. Draw) where this does not work, and there are some keys (e.g. F1 or Esc) that cannot be copy&pasted.

Also, maybe your pointing device is not able to do interclicks?

This solution uses a modified Text viewer that displays OnScreenKeyboard.Text. On a left click, the clicked letter will be inserted (by injecting it into Input.Mod) in lower case, on a right click, it will be inserted in upper case. A middle click will insert the lowercase letter prepended by a space. Clicking on an empty space will insert space, tab or line feed, depending on the mouse button used.

Other keys are available as special keywords to click onto. The F1 keyword can be dragged to the point where F1 should be injected.

For interclicks, there are special keywords too, that will affect the next "real" click.

Installation

  • Apply InjectInput.patch to Input.Mod.

  • Push OnScreenKeyboard.Mod and OnScreenKeyboard.Text.

  • Recompile Input.Mod and all dependencies (including the compiler):

    ORP.Compile Input.Mod/s Oberon.Mod/s ~
ORP.Compile MenuViewers.Mod/s ~
ORP.Compile TextFrames.Mod/s ~
ORP.Compile System.Mod/s ~
ORP.Compile Edit.Mod/s ~
ORP.Compile ORS.Mod/s ORB.Mod/s ~
ORP.Compile ORG.Mod/s ORP.Mod/s ~

  • Compile the new module:

    ORP.Compile OnScreenKeyboard.Mod/s ~

  • Restart the system.

  • Run OnScreenKeyboard.Show.
