- EEDRAW Functions
- ----------------
- File menu:
- ----------
- LoadEEDFile - Prompts for a file name (List question), and reads it
- from the current directory, if SELECT key, abort if ABORT key.
- Note file type must be '.eed'. A new window is created for it and
- the user is prompted to set the window size (see ResizeWindow).
- NewEEDFile - Creates a new drawing window not assosicated with any
- file. This is the way to create new drawings. The user is
- prompted to set the window size (see ResizeWindow).
- SaveAllEED - Saves all unsaved drawings. This is probably useful
- before quiting eedraw.
- SaveEEDFile - Saves currently edited file. This routine can be used
- only after a new file was saved at list once, or it was loaded.
- In both cases, it will be saved on the same name, after
- renaming old one to have '.bak' extension.
- Ask for verification (Yes/No question).
- SaveEEDAsOld - Same as SaveEEDFile, but prompts with list of all '.eed'
- files in current directory, and saved by the name selected if
- SELECT key, or abort if ABORT key.
- SaveEEDAsNew - Same as SaveEEDFile, but prompts for a new file using
- String question.
- SaveNetList - Save a net list for the active window. Default name is
- same as '.eed' but with '.net' type.
- CloseEEDFile - Closes a drawing window associated with a file. Note
- that non of the above saving functions close the window,
- and this function is the only way to close a window.
- Ask for verification if data modified (Yes/No question).
- ClearAll - Clears all eedrawing data in a picked window. The user is
- requested to "click" on the window to clear.
- Ask for verification (Yes/No question).
- Directory - Display content of current directory as in List question.
- both SELECT key and ABORT key can be used to exit this mode.
- Unlike LoadEEDFile, all files are displayed.
- ChangeDir - Prompts with String question for a new directory. Old
- directory is provided to begin with.
- ShellToDos - "Fork"s (I wish this was true...) to the DOS O.S. . Type
- 'exit' at the DOS prompt to return to EEDraw.
- ExitEEdraw - Exits the Program.
- Ask for verification (Yes/No question) and issue a warning
- if not all files were saved.
-
- Window menu:
- ------------
- PopWindow - Pops up a window the user picks. The window is being
- picked by "clicking" on it. ABORT key aborts this operation.
- PushWindow - Pushes down a window the user picks. The window is
- being picked by "clicking" on it. ABORT key aborts this operation.
- MoveWindow - Moves a window the user picks. The window is being
- picked by "clicking" on it. ABORT key aborts this operation.
- The picked window frame is poped up so current position is
- all visible. The cursor prompt changes to a box in the window
- size that the user needs to place as the new position.
- ResizeWindow - Same as MoveWindow but for resizing the window.
- FullSize - Blows up a window the user picks. The window is being
- picked by "clicking" on it. ABORT key aborts this operation.
- This make the window as big as possible in the current
- display device. Calling this function again on the window
- will recover its original size.
- This function may be activated on drawing windows only.
- ShowName - A toggle to show/hide window name. The window name is
- simply the filename the window is associated with. Also
- displayed is O)riginal, M)odified, or S)aved file status
- as O/M/S letters.
- MakeActive - All drawing operations are performed on the active
- window. If only one drawing window exists it is the active
- one. If more, exactly one of them is the active one. This
- function selects the active window by a user pick. The window
- is being picked by "clicking" on it. ABORT key aborts this
- operation.
- NameActive - All drawing operations are performed on the active
- window. If only one drawing window exists it is the active
- one. If more, exactly one of them is the active one. This
- function selects the active window by name. A list query of
- all drawing window (file) names is being poped up and the
- selected becomes the active one.
- PanWindowLeft - Pan the ACTIVE window a half window to the left.
- PanWindowRight - Pan the ACTIVE window a half window to the right.
- PanWindowUp - Pan the ACTIVE window a half window up.
- PanWindowDown - Pan the ACTIVE window a half window down.
-
- Display menu:
- -------------
- ZoomOut - Zoom out (center of screen remains at center) by factor of 2.
- Note that if you zoom out from regular zoom factor, text will
- disappear as it can not be shrinked. You can enable text from
- the Status menu manually.
- ZoomIn - Zoom in (center of screen remains at center) by factor of 2.
- ZoomReset - Reset Zoom value to the regular zoom factor.
- RedrawAll - Redraw all screen.
-
- Libs menu:
- ----------
- LoadLibrary - Prompts for a file name (List question), and reads it
- from the library directory (see ChDirLibrary below), if SELECT key,
- abort if ABORT key. Note file type must be '.lib'.
- LoadLibByName - Loads one or several libraries (seperated by commas)
- by providing their names. To load EPROM.LIB and LINEAR.LIB
- "eprom,linear" should be typed. Libraries are been search in all
- directories as specified by the PATH environment variable.
- FreeLibrary - Prompts with all loaded libraries with List question,
- and frees the selected one if SELECT key, abort if ABORT.
- ViewLibrary - Prompts with all loaded libraries with List question,
- If a library has been selected via SELECT key, prompt with
- all parts defined in this library again with a List question.
- Selection of a part with SELECT key will display it. ABORT will
- go back to library List question, which can be aborted again
- via the ABORT key.
- DirLibrary - Displays content of library directory library files
- (those with '.lib' extension) as in List question.
- both SELECT key and ABORT key can be used to exit this mode.
- ChDirLibrary - Prompts with String question for a new directory
- for library search. Old directory is provided to begin with.
- This directory is used for Load/DirLibrary routines above
- only. LoadLibByName and auto library loading upon eedraw file
- loading will search all ddirectories as specified by the PATH
- environment variable.
-
- Draw menu:
- ----------
- DrawLine - Enters drawing mode. If HVLines is set (see SETUP,
- EEDraw.cfg section), only horizontal/vertical lines are allowed.
- In this mode, pressing SELECT key will insert a new point
- in the created polyline and pressing ABORT will delete the
- last entered point.
- If however, there are no points at all in the current polyline,
- ABORT key will abort this mode.
- Also, pressing SELECT twice (at the SAME place as the last
- point entered) will complete the drawn polyline.
- DrawBus - Same as DrawLine, but draw thicker lines.
- DrawConnect - Draw a connection junction, if SELECT key is pressed,
- or abort if ABORT key is pressed.
- DrawText - Prompts for a string with String question, and then
- position the text horizontally or vertically. If the positioning
- is terminated with ABORT it is ignored, SELECT will update.
- DrawLibItem - Prompts for a part name with String question. If
- this is not the first invocation to this mode, last part will
- be used as default string (remember you can always use Esc to
- clear to a fresh line). If part is found (name is exactly the
- same as shown in the ViewLibrary function above), a pop up
- menu will allow to rotate it 90 degree CW or CCW or mirror it.
- Successive SELECT will transform the library item to the
- desired orientation, while ABORT will abort this DrawLibItem
- mode. SELECT PlaceIt (top menu entry) will allow to position
- the part in the exact place.
- The user is also been prompted for Chip (i.e. 74LS00) and Part
- (i.e. IC7) names if they are required/allowed (see Appendix on
- library file definition) for this part. These are positioned
- similar to the way DrawText position its text, except that
- Chip name is already known and can not be modified.
-
- Modify menu:
- ------------
- This menu is heavily based on Picking objects. a single object
- is being picked if the cursor is on an object. The cursor is
- considered on an object if one of the following:
- A. Line and Bus items: the cursor is on one of the Line/Bus end
- points (any point that was set by SELECT when it was created,
- including internal points).
- B. Connect item: the cursor is on the Connect center.
- C. Text item: the cursor is inside the smallest axes parallel
- bounding box holding this text.
- D. Library item: the cursor is on any polyline end point
- (including internal points).
-
- The picked object will blink. SELECT key will select it, ABORT
- key will cause the next object, if such exists at this position,
- to blink until one is selected via the SELECT key, or no more
- objects can be picked.
-
- If no object at all is found at the cursor point, the point is
- used as first corner of a box to pick a set of objects - a second
- SELECT key will pick the second corner of the box, ABORT key will
- abort this mode. All objects intersect with the defined box, will
- be considered picked, with no more verification.
-
- ModifyMove - Pickes object(s), and moves it (them) to a new
- position. Once the object(s) is (are) picked, SELECT key will
- set its(their) new position, ABORT will leave it unchanged.
- ModifyCopy - Pickes object(s), and copies it (them) to a new
- position. Once object(s) is (are) picked, SELECT key will place
- it(them) in new position, ABORT will abort the copy operation.
- EditLibItem - if the picked object(s) is a single library item,
- allows editing any of the following (via a pop up menu):
- A. Editing the part name. This is the only way to add a part
- name to a library item if the library item has none by
- default.
- B. Toggle to Draw/Undraw chip name (if this chip is allowed
- to have one).
- C. Reposition Chip name (if this chip have one).
- D. Reposition Part name (if this chip is allowed to have one).
- E. Reorient the lib part.
- Picking one of the above via SELECT will allow text
- positioning or text editing (via String question). ABORT or
- selecting Done (first menu entry) will abort this EditLibItem
- mode.
- ModifyDelete - Deletes the picked object(s). The deleted object(s)
- is (are) saved in a special 10 places deep stack, and deleted
- items can be undeleted using the ModifyUnDel function.
- Each of the 10 placed stack can hold any result of a pick
- no matter how many objects are inside.
- This Delete/Undelete mechanism can be used to cut and paste
- even between different files/windows - this stack is never
- being cleared.
- ModifyUnDel - Undelete the last delete operation (see ModifyDelete),
- from the delete stack (LIFO).
- ModifyCut - Same as ModifyDelete, but original is NOT deleted. The
- object is being pushed onto the undelet stack and can then be
- ModifyUnDel, ModifyPaste etc.
- ModifyPaste - Same as ModifyUnDel, but the undelete stack is NOT
- modified. This function enables pasting and placing the same
- object few times.
- ModifyDrop - Drops the top of stack from the undelete stack. May be
- used to drop a cut/paste object sequence from stack.
-
- Status menu:
- ------------
- Help - Pops up an help window and displays the content of
- eedraw.hlp. If the help window is already poped up, this
- function will close it (acts like a toggle.).
- GetMemoryFree - Prompts with a continue question, on the
- current free memory. Getting close to zero is unsafe!
- GetZoomFactor - Allows you to see the current zoom factor
- SetDrawText - Sets drawing of text smaller than minimal size
- (8x8). This will draw text at 8x8 size which is too big,
- but may be sometimes useful.
- SetTextSize - Sets the scaling (up only) of the text size.
- By default this is equal to 1, but up to scaling up by 7
- is allowed.
- SetAutoPan - If TRUE, auto panning will occur when placing
- objects that have been moved off the active WINDOW. The
- object will be place so it is centered in the window.
- SetHVLines - Allows drawing of diagonal lines as well if set
- to FALSE. Uses Yes/No question.
- SetSnapFactor - Sets the invisible grid the cursor position is
- snapped to. You probably do not want to change this,
- especially not in the middle of file editing.
- Uses String question, and display current Snap factor to
- begin with.
-
- Other (not in any menu):
- ------------------------
- SameAgain - Executes the last function again.
- If you have a mouse with 3 buttons, pressing middle button
- will execute this command (hard-bound).
- if you have a mouse with 2 buttons, pressing both buttons
- will execute this command (hard-bound).
