* Add interact_day_item_copy()Lukas Fleischer2012-07-061-0/+12
| | | | | | | This can be used to copy an item, so that it can be pasted somewhere else later. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Duplicate items when pastingLukas Fleischer2012-07-061-2/+3
| | | | | | This allows pasting items more than once. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Revise todo_delete_note_bynum()Lukas Fleischer2012-07-041-1/+1
| | | | | | | Pass an item instead of passing a list item index (analogous to commit 02c90ba53a658686bad5cb5f88c555d9eef06399). Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Implement a cache for the monthly viewLukas Fleischer2012-06-301-0/+13
| | | | | | | | | | | | | | | | | Add a very simple cache, which is used to store the days that contain an event or an appointment. This makes redrawing and browsing the calendar panel much faster. The cache has a size of 31 integers (which is equivalent to 124 bytes on a 32 bit system and 248 bytes on a 64 bit system) and invalidates itself if the current month has changed. If an item is added/changed/removed, the cache needs to be invalidated manually by calling calendar_monthly_view_cache_set_invalid(). Note that this will always invalidate the whole cache, even if only one item at the last day of the month was removed. This is a trade-off between simplicity and efficiency.

* Remove unneeded parameter/return valueLukas Fleischer2012-06-301-6/+3
| | | | | | | | The item type parameter/return value no longer needs to be passed/returned to interact_day_item_{paste,cut}(), since the type descriptor is saved when cutting an item now. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Revise cut/pastingLukas Fleischer2012-06-301-10/+40
| | | | | | | | | | | | | | | | Instead of calling type-specific duplication handlers and inserting clones of the original items when pasting, save the generic day item and remove the actual item from the linked list, so that it can be inserted anywhere else later. The cut/paste buffer is moved to the interaction unit, item-specific cut operations are changed to remove the item from the linked list only instead of copying and freeing it. An item is only freed if another item is cut before the current cut/paste buffer is pasted. All paste operations are changed and reinsert the actual item instead of creating a clone.

* Move apoint_{cut,paste}() to interaction unitLukas Fleischer2012-06-301-0/+51
| | | | | | | | These functions get the current selection, call day_*_item() and fix the current selection on the appointment panel, so move them where they belong. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Revise *_delete{,_bynum}()Lukas Fleischer2012-06-301-6/+5
| | | | | | | | Always pass an item instead of passing a date and a index. This makes use of the NULL callback that was added with one of the previous patches. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Rename interaction functionsLukas Fleischer2012-06-301-10/+10
| | | | | | | | Rename all interaction functions for the sake of consistency and add a "interact_" prefix. Also, mark day_erase_item() static since it is not used anywhere else. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Move interaction functions to a separate fileLukas Fleischer2012-06-301-0/+861
This is a first step to clean up several compilation units and separate the front end from back-end operations. All functions that require user interaction are moved to a new compilation unit "interaction.c". Also, following things are adjusted to the new layout: * Make day_item_get_*() and a few other functions public, so that it can be accessed from the new compilation unit. * Use apoint_hilt(), todo_hilt(), etc. instead of directly accessing static variables.
