* Key bindings for UTF-8 encoded charactersLars Henriksen2018-06-031-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Internally characters (keys) have two representations: integers and key names. Key names are characters strings, usually the name of the character; e.g., the character A has the representations 65 and "A", and the tab character the representations 9 and "TAB". The function keys_int2str() turns the integer representation of a key/character into the key name. For display purposes the key names are usually confined to have display width at most three. Some curses pseudo-keys have longer key names; e.g., the back-tab character is "KEY_BTAB". A long key name makes a character difficult to recognize in the status bar menu. The key name of a multibyte, UTF-8 encoded character is the conventional Unicode name of the code point; e.g., the character ü has key name "U+00FC" because ü is the code point 0xFC. Most of these look alike in the status bar menu. The patch makes the key name of a multibyte character look like that of a singlebyte character: the character itself, i.e. the key name of the character ü is "ü". The main tool is implementation of a utf8_encode() routine. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>

* Scrollbar and right window border (corrected)Lars Henriksen2018-05-261-5/+5
| | | | | | | | | | | | | | | | | When a scrollbar is on display in APP or TOD windows, the right vertical border (outside the scrollbar) is not highlighted when the window is selected. The scrollbar is always highlighted: - when APP or TOD is deselected - in configuration windows where borders otherwise are not The patch moves the scrollbar parameters (except highlight) from arguments of draw_scrollbar() to the function itself. The highlight argument was 1; instead it is set higher in the call hierarchy (wins_update_panels()) and passed on down. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Transparent cursor fixLars Henriksen2018-05-261-6/+5
| | | | | | | | | | | | | Commit f8e6e0d (Fix no-colour theme, 2017-12-10) partly destroyed the cursor in getstring() by turning it into a solid block. The fix reintroduces wchgat() which requires a color pair argument. When no colors are wanted, color pair 0 is used. A similar problem exists in the layout and colour customization windows and is fixed in the same way: move to the position and apply the reverse video attribute.

* Use dummy variables to ignore return values of pair_content()Lukas Fleischer2018-05-101-2/+2
| | | | | | | | This prevents from segmentation faults with recent ncurses implementations. See commit 5722d2e (Fix segmentation fault when changing colors, 2017-07-28) for details. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Default colour as foreground colourLars Henriksen2017-12-101-3/+12
| | | | | | | | | | | | | In the default colour setup (white on black), white could only with great difficulty be used as customized foreground colour, because the colour pair COLR_CUSTOM then was identical to COLR_DEFAULT (default on default). This made it impossible to distinguish the selected element in lists. The patch turns on the video attribute bold when default is chosen as foreground colour.

* Function cleanup in custom.cLars Henriksen2017-11-231-39/+39

* Fix multiple popup windowsLars Henriksen2017-10-291-11/+7
| | | | | | | | | | The window was not deleted if an "already in use"-key was detected, and a new one was created as the loop was reentered. Create/delete of the popup are moved outside the loop. A redrawwin() call is needed to have the window displayed again. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Remove recognized keys checkLars Henriksen2017-10-261-36/+12
| | | | | | | All keys known by ncurses can be bound. Thus the check for not recognized keys in custom_keys_config() becomes superfluous. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Updates for UTF-8 key bindingsLars Henriksen2017-10-231-6/+12
| | | | | | | | | | | | | | | | | | | | | Code point mapping adjusted for multibyte characters to avoid the ncurses range 0-KEY_MAX. This includes three fixes: 1) test sequence in keys_assign_binding(), 2) reassemble multi-byte character in keys_wgetch(), 3) check for already in use in keys_assign_binding(). Rearrangement of code. The introduction of allocated memory in keys_int2str() has as a consequence that check for recognized ncurses pseudo characters now are in two places: keys_str2int() and custom_keys_config(). The latter was moved from keys_wgetch() to improve user information. More informative warning messages in custom_keys_config(). Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Make the day heading position configurableLars Henriksen2017-09-081-1/+23

* Add a function to wait for any key pressLukas Fleischer2017-09-031-1/+1
| | | | | | | Introduce a new function keys_wait_for_any_key() and use it instead of wgetch() whenever the return value is discarded. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Improve default selection when editing key bindingsLukas Fleischer2017-09-031-4/+4
| | | | | | | | When adding a new key binding, automatically select the new binding. When removing a key binding, keep the selection index (unless the last binding of a row is removed). Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Use strncpy() properly in general_option_edit()Lukas Fleischer2017-09-031-6/+8
| | | | | | | Always use strncpy() to copy strings between fixed-size buffers and pass the buffer size as maximal length parameter. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Add support for UTF-8 key bindingsLukas Fleischer2017-08-301-2/+2
| | | | | | | | | | | | | | | | A new function keys_wgetch() reads full UTF-8 characters instead of single ASCII characters only. Key bindings for regular ASCII characters are stored in a hash map while the actions of keys with higher code points are stored in a linked list for space efficiency. The key serialization methods are updated to handle UTF-8 characters as well; extended UTF-8 characters (characters not in the ASCII range) are serialized by using the hexadecimal representation of the corresponding code points (e.g. "U+00E4").

* Fix segmentation fault when changing colorsLukas Fleischer2017-07-281-3/+3
| | | | | | | | | | | | | | | | The pair_content() function can be used to retrieve a color pair. The foreground and the background color numbers are written to addresses specified by the second and third parameters. While both parameters were optional in older ncurses implementations (making it possible to pass NULL pointers if the one does not care about either foreground or background color), recent implementations seem to assume that both parameters are valid pointers. Thus, instead of passing NULL, we need to pass a pointer to a dummy variable when we do not care about the background color. Partly fixes GitHub issue #31.

| | | | | | | | | This changes the general options menu to use the new generic list box implementation.

* Rework scroll window implementationLukas Fleischer2014-05-181-41/+19
| | | | | | | | | | This complete rewrite of the scroll window implementation decouples scroll windows from every other window abstraction layer we use. Note that this leads to some code duplication. The long-term purpose of this rewrite, however, is to eventually make every panel use scroll windows. This makes for a huge cleanup of the UI code.
