Properties
IntegerComponent_State
from nesting.pkg
Booleanentry_refresh_State
required by dds
IntegerHas_Components_State
IntegerOrdering
initial ordering
BooleanpbAutoRegenerate
if false it will never try to reorder your additions
BooleanpbPromptListBehavior
determines behavior of various grid vs prompt list
BooleanpbStaticData
if true, load all data at once and it is static
BooleanpbUnOrdered
tracks if new records might have made the list out of order
IntegerpeRequestFindMode
determines how request_find behaves
Functions and Procedures
IntegerAdd_Focus(Handle hoParent)
BindDataSource()
use this to set any special properties in the datasource that might be
needed for this particular grid and data source. With db grids we need to
update the Server, Main_file and Ordering
ChangeOrdering(Integer iOrdering Boolean bDescending)
IntegerCheckbox_item_State(Integer iItem)
required DD/DEO interface
Construct_Object()
Copy_Item_Options(Integer iDSO Integer iFile Integer iField Integer iDEO Integer iItem)
required DD/DEO interface
HandleCreateContextMenu()
default context menu for db grids
HandleCreateDataSource()
called by constructor
IntegerData_Field(Integer iItem)
required DD/DEO interface
IntegerData_File(Integer iItem)
required DD/DEO interface
StringData_Value(Integer iItem)
required DD/DEO interface
DataLoadAdjustOnAddFocus()
IntegerDDRefreshTableStatus(Integer iTable)
returns the table's status for the refresh event. A table can either be
cleared, found or not touched by the operation. This can only be called while
within Refresh. This was created to hide the private is_file_included command
BooleanDEO_Control_Object()
required DD/DEO interface
BooleanDeo_Find_Object()
required DD/DEO interface
BooleanDEO_Object()
required DD/DEO interface
HandleDEOColumnObject(Integer iColumn)
returns object for column. If the column object is not a DEO it returns 0
Entry_update(Integer iFile Integer iDoAll)
required DD/DEO interface
sent by DD before a find and save. We only care about DD finds which
means DoAll is 1
IntegerExiting(Handle hoDestination)
augment to refresh the grid if it is unordered after a save. Generally upon
exit we want to grid refreshed else OnIdle may do this when the grid does not have
the focus which can change other DEOs that rely on this grid.
IntegerExtended_deo_State()
required DD/DEO interface
File_Field_Label_Changed(Integer iFile Integer iField Boolean bLong String sLabel)
required DD/DEO interface
File_Field_mask_Changed(Integer iFile Integer iField String sMask)
required DD/DEO interface
File_Field_Option_Changed(integer iFile integer iField integer iOptions integer bClear)
required DD/DEO interface
sent by DD whenever DD option has changed.
File_Field_Value_Changed(Integer iFile Integer iField String sValue Integer iChangeDisabled)
required DD/DEO interface
sent by DD whenever DD value has changed.
Find_First()
required DD/DEO Find interface
Find_GE()
required DD/DEO Find interface
Find_Last()
required DD/DEO Find interface
Find_Next()
required DD/DEO Find interface
Find_Previous()
required DD/DEO Find interface
HeaderReorder(Integer iCol)
StringItem_Field_Property(Integer iMsg Integer iItem)
required DD/DEO interface
IntegerItem_Noput(Integer iItem)
required DD/DEO interface
HandleItemToDEOColumnObject(Integer iItem)
IntegerLoadByMatchingRow(RowID riID Boolean bResetCache)
Load grid based on rowId. If bResetCache the cache is cleared so the
search always refreshed. If false, it tries to find the ID in the existing
datasource first.
OnIdle()
Handleprototype_object()
required DD/DEO interface
Refresh(Integer eMode)
required DD/DEO interface
sent by DD when there is a clear/find/save/delete
RefreshDataFromDD(Integer iOffset)
Refreshes grid around the DD record. You'd use this if you've got a newly empty activated grid or a
deferred grid
This always refreshes the cache
RefreshDataFromExternal(Integer iOffset)
Refreshes grid around the current file buffer
This always refreshes the cache
RefreshDataFromMatchingRow(RowID riID Integer iOffset)
Refreshes grid around this row id. Allows you to refresh a grid around record.
This always refreshes the cache
RefreshDataFromSelectedRow()
Refreshes grid around selected row id
IntegerRelatingField(Integer iRelatedFile)
Attempt to find the field from the server's MainFile that relates to iRelatedFile
ReorderGridByColumn(Handle hoCol Boolean bDescending)
Request_Cancel()
Request_Clear_All()
Request_Find(Integer eFindMode Integer bEntUpdt)
required DD/DEO Find interface
Request_Save_No_Clear()
A grid save *is* a no-clear save so you don't really need to use this. However this message is supported in DEO controls
and we want it to work if this is sent from a hot-key, menu or toolbar item.
RequestColumnFind(Integer iCol Integer eFindMode Integer bEntUpdt)
RequestColumnLookup(Integer iCol)
does a find for the passed column by first looking down and, if no find, then looking up
This is used when you are doing lookup/searches
RequestColumnSearch(Handle hoCol Integer iKeyCode Integer iKeyShift)
do a popup search request for the passed column. The keys can provide a
seed value - they come from OnComKeyDown. Augmented to do a file find with
DB grids
Set(Integer newVal)
this procedure **replaces** set Changed_state from the server mixin. We are not going to set
the watched server's (parent DDs) to changed_state. This is not needed and is heavy handed because
this sets all watched servers and not the single column that triggered the change. We probably don't
need to set watched servers in the grids. We are setting the main server's DD to changed and that is enough
update_dependent_items()
required DD/DEO interface
Update_focus_field()
required DD/DEO interface
sent by DD to commit the focused value
IntegerValidate_Items(Boolean bNotFindReq)
required DD/DEO interface
