arealist_pro_v10_modified_properties
The following properties have been modified in AreaList Pro v10.
Area properties
| property | can read | can write | persi stent | type | default | min | max | usage |
|---|---|---|---|---|---|---|---|---|
| ALP_Area_WindowsClip | √ | √ | bool | no | Deprecated since v10 (unused in ALP 10) | |||
| ALP_Area_CopyOptions | √ | √ | √ | int | 0 | 0 | 7 | Options for Copy & Drag (made 3-bit to support CSV and hidden columns) bit 0 = include headers bit 1 = CSV encode bit 2 = include hidden columns (as ALP_Area_CopyHiddenCols, kept for compatibility) |
| ALP_Area_DragScroll | √ | √ | √ | int | 30 | -1 | 30 | Size of frame around the AreaList Pro area border where dragging will start area scrolling When the user drags something near the AreaList Pro area border, the contents will be scrolled -1 = “no scroll” (both directions) when dragging a row or a cell |
| ALP_Area_Event_Filter | √ | √ | int | 0 | 0 | 15 | Mask to define which events should not be reported bit 0 (value 1) = don’t report AL Mouse moved event bit 1 (value 2) = don’t report keyDown/autoKey (if bit 1 is zero, keyDown event is reported to the callback) bit 2 (value 4) = don’t report AL Vertical Scroll Event bit 3 (value 8) = report AL Horizontal Scroll Event |
|
| ALP_Area_SendEvent | √ | √ | int | Set custom event and execute the object method (and event callback if set) ALP_Area_AlpEvent will contain this event, ALP_Area_Event will be 0 Use e.g. -100 to not confuse your own code with regular AreaList Pro event codes Usable in subforms to CALL SUBFORM CONTAINER ALP_Area_SendEvent returns the first event in the queue (getter), adds requested event to the end of the queue (setter) Events are sequentially reported Note: when an event callback (ALP_Area_CallbackMethOnEvent) is installed, the event is reported immediately (except during update), the object method may fail to be executed… use event callbacks! Horizontal and vertical scroll events are cumulated and moved to the end of the queue (e.g. using mouse wheel, many scroll events can be reported, but actually the object method can’t be executed during mouse wheel event and the event is reported at next idle → will be reported only once, not many times after ending the scroll) Two identical events are never put into the queue |

| ALP_Area_ShowVScroll | √ | √ | √ | int | 1 | 0 | 3 | Show vertical scrollbar 0 = manual not shown 1 = manual shown 2 = automatic, not shown 3 = automatic, shown Note that “auto” vs “manual” differs from ALP_Area_ShowHScroll usage for compatibility reasons |
| ALP_Area_ShowColDividers | √ | √ | √ | int | 0 | 0 | 15 | Show column dividers (using ALP_Area_ColDivColor): bit 0 (value 1) = draw over data and footer bit 1 (value 2) = hide footer dividers (bit 0 ignored if bits 0 and 2 are 0) bit 2 (value 4) = draw last column divider bit 3 (value 8) = hide column dividers in the empty area below last row |
| ALP_Area_ShowRowDividers | √ | √ | √ | int | 0 | 0 | 3 | Show row dividers (using ALP_Area_RowDivColor) Made 3-state: 0 = no 1 = yes 3 = yes, but not in empty area below last data row Set bit 0 to 1 (add value 1) to draw row dividers and bit 1 to 1 (add value 2) to hide row dividers in the empty area below last row |
Column properties
| property | can read | can write | persi stent | type | default | min | max | usage |
|---|---|---|---|---|---|---|---|---|
| ALP_Column_Type | √ | √ | int | 0 | 38 | Data type (added values for Is Pointer, Is BLOB and Is Object – not displayed but can be used to keep in sync with displayed columns) 0 = Is Alpha Field 1 = Is Real 2 = Is Text 3 = Is Picture 4 = Is Date 6 = Is Boolean 8 = Is Integer 9 = Is LongInt 11 = Is Time 23 = Is Pointer 30 = Is BLOB 38 = Is Object |
||
| ALP_Column_Format | √ | √ | √ | text | When using ALP_Column_DisplayControlType = 4 (draw pictures), old format expected for “True;False;Mixed” now it allows “+offset;value0;value1;…;valueN” The plus sign makes the difference in the interpretation of the values Is used as: take current value, add offset, use it as index into the array Examples • for old tri-state Boolean “+0;False;True;Mixed” • for “five-star rating” from 0-5: “+0;1200;1201;1202;1203;1204;1205” Zero will display icon 1200, 5 will display icon 1205 |
