- /* $Log: timer.c,v $
- * Revision 2.13 92/09/12 18:43:41 drapeau
- * Replaced non-portable "irint()" function with simple cast-to-integer syntax.
- *
- * Revision 2.12 92/05/14 15:43:42 drapeau
- * * Updated copyright information.
- *
- * Revision 2.11 92/01/09 18:25:31 drapeau
- * Slight modifications to make code ANSI-compliant.
- *
- * Revision 2.10 91/12/31 18:46:03 drapeau
- * Removed the inclusion of string.h, since XView will include the
- * appropriate definitions.
- *
- * Revision 2.0 91/09/30 15:02:49 derek
- * Version number changed to 2.0.
- *
- * Revision 1.9 91/09/15 20:06:36 derek
- * The following things are done:
- * 1. The foreground of mainTextPane and Quote Window are set to be black.
- * Also, the color of all the text fields are set to black.
- * 2. Now the quoted text will be shown directly on the Quote Window
- * when a panel-item selection is made. The text will also be shown
- * while the author is highlighting a selection in the text window.
- * 3. The inconsistency problem regarding text selection is being taken
- * care of. When the mouse cursor re-enters the text window,
- * the selection will be highlighted again.
- * 4. When the play button is pressed, the text currently selected
- * in the text window (rather than the text initially associated
- * with the edit) will be displayed.
- * 5. The name of the menu_option "Show Quote Window Specifications panel"
- * is shortened to be "Quote Window Options ..."
- * 6. A notify_interpose_destroy_func() is being added to fix the bug
- * that QuoteMaker might exit without killing the Quote Window (which
- * is also a base window).
- * 7. When a different font family or font style is selected, the change
- * will be automatically be reflected on the Quote Window (without the
- * need to "play" the edit in order to verify the font). For font
- * size, the change will be reflected when either a return character is
- * entered at the text field or when one of those numeric "arrows"
- * are pressed.
- * 8. The play button will now flash when an edit is being played.
- * Pause button will also glow when playing is paused.
- * 9. In the course of playing, when another edit is selected,
- * the playing will be stopped.
- * 10. I have used Saber to clean up the code.
- * 11. The left-over "NewEditListPopUp" window is removed.
- * 12. The bug that when quote window is iconified, it wont be un-iconified
- * when the edit is played in timeline, is fixed.
- * 13. The DurationEstimate function is changed so that it no longer
- * needs an edit to be selected first. It will take textWindowStart
- * and textWindowEnd directly as input parameters.
- *
- *
- *
- * Revision 1.8 91/09/05 15:48:07 derek
- * The following changes are made:
- * 1. The name "Quoted Text Window" has been changed to "Quote Window"
- * in the app.
- * 2. ShowApplication() and HideApplication() is changed because of the
- * the change of quote window from a popup to a basewindow.
- * 3. The QuitProc of QuoteMaker is fixed so that the quote window,
- * as a base window, will be destroyed separately.
- * 4. Now hitting return in the label field will not result in adding
- * a new edit.
- * 5. Copyright messages are included in front of every .h and .c file.
- * 6. The scrollbar and the footer of the Quote Window are hidden.
- * 7. I have changed the include openpanel.h statement in QuoteMaker.c
- * to include Browse.h.
- * 8. The delete bug corresponding to the change that the panel-list
- * must have a choice -- is fixed. Also, the corresponding bug
- * for deleteAll is also fixed.
- * 9. Now, deleteAll and deletion of the last item in Panel_list
- * will cause the panel-list to be destroyed and a new one will
- * be created.
- * 10. GetOpt files have been removed from the directory. Corresponding
- * changes are made.
- * 11. The start and end byte fields are removed from the main panel.
- * 12. I have put iconify, hide and show quote window to be buttons
- * instead of menu options.
- * 13. I have removed the PreviewPanelPopup and incorporated its features into
- * the main panel. The three buttons: pause, play and stop and
- * the DurationGauge are moved to the main panel. But the
- * StatusMessage is removed.
- * 14. The EnableLocationChange and EnableSizeChange choice setting
- * are removed. There are no longer such choices.
- * 15. Right now if a panel-item is selected and if another panel-item
- * is picked, the DeselectList() operation in the middle is
- * eliminated. This operation involves updating of text fields and
- * messages and its removal speeds up the program. The panel-list
- * must now take at least one choice. (A choice must be selected
- * whenever there is at least one item on the list). And now
- * there is no way to deselect a list by the user.
- * 16. The "modified bit" associated with the CurrentSelectionNumberLabel
- * is implemented. Now, if a selection is picked, and if either
- * the quote window is moved or any text fields are changed, the
- * modified bit will be on.
- * 17. The Show-text-window button and the Show-quote-window-specifications-popup
- * button are removed. They are now menu options under the Options Menu.
- * 18. The Modify button has its name changed to "Update Edit".
- *
- * Revision 1.7 91/08/27 14:37:42 derek
- * The following things are done:
- * 1. The QuotedTextWindow is changed from a base window to a popup window
- * (now it's called QuotedMaker_quotedTextBaseWindow). I have also
- * added a few options: show, hide and iconify QTW and also created
- * an icon for QTW.
- * 2. The quoted text will be set in PerformSelection() instead of
- * in SetSelection().
- * 3. I have changed the Document field and the EditList field of
- * QuoteMaker so that they will display fill paths.
- *
- * Revision 1.6 91/08/26 12:10:26 derek
- * The following things are done:
- * 1. I have added a few notice_prompts to the linkProtocol (network)
- * functions to give warnings about invalid document names.
- * 2. The quoted text window will by default be hidden during "blank"
- * times. ie. when it is not displaying any text. The interface has
- * been changed so that it now has a HideQuotedTExtWindowAfterPreview
- * check box. The QuotedTextWindow will either stay on the screen
- * or be hidden as the author desires.
- * 3. Make the changes corresponding to the changing of name from OpenPanel
- * to Browse.
- * 4. The return value bug for OpenHandler, SaveHandler is fixed.
- * 5. I have changed the code so that Save and SaveAs will behave correctly.
- * The SaveAs PopUp/Open PopUp are removed. Browse check is
- * incorporated in the applications.
- * 6. The QuoteMaker file format has been changed. An EditNumber field
- * has been added.
- * 7. Changes corresponding to the return value by OpenDoc and SetSelection
- * are made.
- * 8. GetAppIcon() has been implemented.
- * 9. Fonts specified in the Edit-list will be preloaded in OpenDoc().
- * This will hopefully eliminate the startup delay needed to load
- * the font when we put text onto the Quoted TExt Window for the
- * first time.
- * 10. The "play" button will now play things specified in the
- * QuotedTExtWindowSpecificationsPopUp (instead of those specified
- * in the editList).
- * 11. The show selection button is replaced by the set selection button.
- * The Set Selection button willl now not only set the current
- * edit parameters but will also highlight the corresponding section
- * in the text. Also, when one item on the panel-list is clicked on,
- * the corresponding segment in the text will also be highlighted.
- * 12. Notify events which tells the app to show the size and location
- * of the Quoted Text Window are set up. ie. those text-fields
- * on the interface will be updated instantaneously.
- * 16. editList.label is being sent across the network.
- * 17. The title bar and the footer of the QuotedTExtWindow are hidden.
- *
- * Revision 1.5 91/07/15 12:20:19 derek
- * 1. I have added font selection panel to the application.
- * Now a user can specify a font by choosing a font family, a font
- * style and font size.
- * 2. Location and size fields are added to the application. User
- * can specify the size and location of the QuotedTextWindow.
- * 3. A duration estimate button is added to estimate how long the
- * the quoted text should last.
- * 4. Interface has been redesigned to accomodate the addition of
- * font, size and location functionalities.
- * 6. EditList file format has been changed to accomodate the new
- * fields. They are: location (x,y), width, height, font family,
- * font style, font width for QuotedTextWindow.
- * 5. Two timers have been added in an attempt to ensure accuracy
- * of gauge-updating in the preview panel.
- * 6. Command line args are now supported.
- * 7. I have cleaned up the code by using saber.
- * 8. Several bugs from previous revision are fixed.
- *
- *
- * Revision 1.4 91/07/02 15:08:00 derek
- * QuoteMaker now fully speaks the new MAEstro protocol.
- *
- * Revision 1.3 91/07/01 19:12:02 derek
- * The following things are done:
- * 1. The interface is redesigned. Duration fields are added to each
- * edit list.
- * 2. The function panel (functions Window) is implemented. The
- * application is now capable of being "played", "stopped"
- * and "Paused". The sense of "time" is now complete.
- * 3. Makefile fixed.
- * 4. Declaration errors left by previous author are cleaned up.
- * 5. Redundant malloc statements removed. Certain other
- * functions are changed to improve code efficiency.
- * 6. Code cleaned up by saber. Removed redundant variables.
