| 1 | + | ## About | |
| 2 | + | ||
| 3 | + |  TCalendarLite is a lightweight calendar component, a TCustomControl descendant which consequently is not dependent on any widgetset. It is not a fixed-size component, as are most calendars, but will align and resize as needed. Various properties give access to almost every aspect of its appearance. | |

| 13 | + | ## Download and Installation | |
| 14 | + | ||
| 15 | + | #### Release version | |
| 16 | + | ||
| 17 | + | A zip file with the most recent release version can be found at [Lazarus CCR at SourceForge](https://sourceforge.net/projects/lazarus-ccr/files/CalLite/). Unzip the file into any folder. | |
| 18 | + | ||
| 19 | + | The current release version is 0.3.1 | |
| 20 | + | ||
| 21 | + | #### Development version | |
| 22 | + | ||
| 23 | + | Use an svn client to download the current trunk version from [<svn://svn.code.sf.net/p/lazarus-ccr/svn/components/callite/>](svn://svn.code.sf.net/p/lazarus-ccr/svn/components/callite/) | |
| 24 | + | ||
| 25 | + | #### Version Notes | |
| 26 | + | ||
| 27 | + | - **v0.3.10** breaks existing code relying on `TDayOfWeek` starting at value 1. This had to be changed to start at 0 to fix compilation with FPC 3.3.1. | |
| 28 | + | ||
| 29 | + | #### Installation | |
| 30 | + | ||
| 31 | + |  In Lazarus, go to *"Package"* \> *"Open Package File .lpk"*. Navigate to the folder with the callite sources, and select **callight_pkg.lkp**. Click *"Compile"*, then *"Use"* \> *"Install"*. This will rebuild the IDE (it may take some time). When the process is finished the IDE will restart, and you'll find TCalendarLite in the component palette **[[Misc tab|Misc]]**. | |
| 32 | + | ||
| 33 | + | ## Navigation | |
| 34 | + | ||
| 35 | + | - Click on any date | |
| 36 | + | - Use the arrow keys on the keyboard | |
| 37 | + | - Click on the arrow keys above the calendar; the single arrow advances by one month, the double arrow advances by one year | |
| 38 | + | - Click on the month name to open a popdown menu with month names, or click on the year number to open a popdown menu with the last and next ten years. | |
| 39 | + | ||
| 40 | + | ## Multi-selection | |
| 41 | + | ||
| 42 | + | If the property `MultiSelect` is set to `true` then several days can be selected in the calendar. All selected days are drawn with a highlighted background. Multi-selection is controlled by holding special keys down while selecting a day either by a mouse click or a key press: | |
| 43 | + | ||
| 44 | + | - **CTRL**: If the <span class="kbd">CTRL</span> key is pressed while selecting another day then this day is added to the selection. This way a non-contiguous array of dates can be selected. | |
| 45 | + | - **SHIFT**: If the <span class="kbd">SHIFT</span> key is held down during day selection then all day between the prevsiously and the currently selected day are added to the selection. | |
| 46 | + | - **Double-click**: A double click on a workday selects all workdays of the same week. Holding the <span class="kbd">CTRL</span> or <span class="kbd">SHIFT</span> key down extends the selection by the workdays of one or more weeks. | |
| 47 | + | - The selection can be extended into neighboring months if the arrow keys of the keyboard are pressed with the <span class="kbd">CTRL</span> key held down. | |
| 48 | + | - Selection is cleared if any date is selected without pressed any of these keys, or if the arrows or dropdown menus in the top bar are used. | |
| 49 | + | - If previously selected days are added for a second time then they are unselected. | |
| 50 | + | ||
| 51 | + | At **run-time**, the selected data can be controlled or queried by these methods of the calendar: | |
| 52 | + | ||
| 53 | + | - `procedure AddSelectedDate(ADate: TDate)` - adds the specified date to the list of selected dates | |
| 54 | + | - `procedure ClearSelectedDates` - clears all selected dates | |
| 55 | + | - `function IsSelected(ADate: TDate): Boolean` - returns `true` when the given date is selected, `false` otherwise. | |
| 56 | + | - `function SelectedDates: TCalDateArray` - returns an array of TDate elements which contains the selected dates. | |
