In questo post vediamo come creare una form selezione / deselezione, come quelle che c'è sui batch group per esempio:
La form inoltre avrà anche un campo per poter filtrare il nome degli elementi
Per creare queste form AX mette disposizione l'oggetto "SysListPanelRelationTableCallback"
Allo scopo occorrono 3 Tabelle:
1) Anagrafica dei gruppi (LILGroupTable)
2) Anagrafica degli elementi che assegneremo di volta in volta ai gruppi (LILElementTable)
3) Tabella che contiene il legame (LILGroupElementTable), che sarà interemente gestita tramite l'oggetto "SysListPanelRelationTableCallback"
Ogni elemento inoltre potrà appartenere contemporaneamente a più di un gruppo alla volta.
Le tre tabelle saranno così fatte:
Definiamo a questo punto una nuova form con il seguente design:
[Form]
class LILGroupElementInfo extends FormRun
{
SysListPanelRelationTableCallback sysListPanel;
Num groupId;
Description elementNameFilter;
public void close()
{
sysListPanel.finalize();
super();
}
void init()
{
#ResAppl
sysListPanel = SysListPanelRelationTableCallback::newForm(element,
element.controlId(formControlStr(LILGroupElementInfo, ListPanelGroup)),
"@SYS113180", "@SYS78228", #ImageUser,
tablenum(LILGroupElementTable),
fieldnum(LILGroupElementTable, ElementId),
fieldnum(LILGroupElementTable, GroupId),
tablenum(LILElementTable),
fieldnum(LILElementTable, ElementId),
[fieldnum(LILElementTable, ElementId), fieldnum(LILGroupTable, Description)],
fieldNum(LILElementTable, Description), '',
identifierstr(Validate), '', '');
sysListPanel.parmDataRangeAsFilter(true);
super();
sysListPanel.init();
}
public edit str elementNameFilter(boolean _set, str _elementName)
{
if (_set && _elementName != elementNameFilter)
{
elementNameFilter = _elementName;
}
return elementNameFilter;
}
void tabChanged(int fromTab, int toTab)
{
#define.TabGroups(1)
#define.TabGroupElement(2)
groupId = LILGroupTable.GroupID;
switch (toTab)
{
case #TabGroups:
break;
case #TabGroupElement:
sysListPanel.parmDataRangeValue(elementNameFilter ? elementNameFilter : '*');
sysListPanel.parmRelationRangeValue(LILGroupTable.GroupID);
sysListPanel.parmRelationRangeRecId(LILGroupTable.RecId);
sysListPanel.fill();
break;
}
}
boolean validate(userId _userId, AddRemove _addRemove, SysListPanelRelationTable _listViewHandler)
{
return true;
}
[DataSource]
class LILGroupTable
{
public boolean validateWrite()
{
boolean ret;
str leftTrimedGroupId;
str rightTrimedGroupId;
leftTrimedGroupId = strltrim(LILGroupTable.GroupID);
rightTrimedGroupId = strrtrim(leftTrimedGroupId);
LILGroupTable.GroupID = rightTrimedGroupId;
ret = super();
return ret;
}
int active()
{
int ret;
ret = super();
element.elementNameFilter(true, '');
element.tabChanged(0, tab.tab());
return ret;
}
}
[Control("Tab")]
class Tab
{
void tabChanged(int fromTab, int toTab)
{
element.tabChanged(fromTab, toTab);
super(fromTab, toTab);
}
}
[Control("TabPage")]
class Groups
{
public boolean allowPageDeactivate()
{
boolean ret;
ret = super();
if (!LILGroupTable.RecId)
{
if (LILGroupTable_ds.validateWrite())
LILGroupTable.write();
else
return false;
}
return ret;
}
}
[Control("Button")]
class FilterButton
{
public void clicked()
{
super();
sysListPanel.parmDataRangeValue(elementNameFilter ? elementNameFilter : '*');
sysListPanel.fill(true);
}
}
}
Il risultato sarà il seguente:
Occorre:
1) Creare una tabella che conterrà i valori selezionati che chiameremo LILDlvModeAssociation così fatta:
2) Estendere la classe sysPanel così:
public final class LILSysListPanel_VendDlvModeAssociation extends SysListPanel
{
public void addData(container _data)
{
int i;
LILDlvModeAssociation relation;
DlvMode dlvMode;
for (i = 1; i <= conlen(_data); i++)
{
relation.DlvModeRecId = conpeek(_data, i);
relation.DlvModeId = DlvMode::findRecId(relation.DlvModeRecId).Code;
relation.insert();
}
}
public container getData()
{
container selectedData;
container availableData;
LILDlvModeAssociation relation;
DlvMode dlvMode;
while select TableId from relation
join RecId, Code from dlvMode
where dlvMode.RecId == relation.DlvModeRecId
{
selectedData += [[dlvMode.RecId, dlvMode.Code]];
}
while select RecId, Code from dlvMode
order by Code
notexists join relation
where relation.DlvModeRecId == dlvMode.recId
{
availableData += [[dlvMode.RecId,dlvMode.Code]];
}
return [availableData, selectedData];
}
public int numOfColumns()
{
return 2;
}
public void removeData(container _data)
{
int i;
RefRecId dlvModeRecId;
LILDlvModeAssociation relation;
for (i = 1; i <= conlen(_data); i++)
{
ttsBegin;
dlvModeRecId = conpeek(_data, i);
delete_from relation
where relation.DlvModeRecId == dlvModeRecId;
ttsCommit;
}
}
public static LILSysListPanel_VendDlvModeAssociation construct()
{
return new LILSysListPanel_VendDlvModeAssociation();
}
internal static SysListPanel newForm(FormRun _formRun,
int _parentId)
{
LILSysListPanel_VendDlvModeAssociation sysListPanel = LILSysListPanel_VendDlvModeAssociation::construct();
sysListPanel.parmFormRun(_formRun);
sysListPanel.parmParentId(_parentId);
sysListPanel.parmCaptionSelected("@SYS113180");
sysListPanel.parmCaptionAvailable("@SYS179894");
sysListPanel.parmHasAddAllButton(true);
sysListPanel.parmHasRemoveAllButton(true);
sysListPanel.parmHasUpDownButton(true);
sysListPanel.build();
return sysListPanel;
}
protected FormListSort sortMethod()
{
return FormListSort::NoSort;
}
}
4)Fare la CoC sulla form VendParameters:
[ExtensionOf(formStr(VendParameters))]
final class LILVendParameters_Form_Extension
{
public LILSysListPanel_VendDlvModeAssociation sysListPanelDlvMode;
public LILSysListPanel_VendDlvModeAssociation parmSysListPanel(LILSysListPanel_VendDlvModeAssociation _sysListPanelDlvMode = sysListPanelDlvMode)
{
sysListPanelDlvMode = _sysListPanelDlvMode;
return sysListPanelDlvMode;
}
public void init()
{
next init();
this.initListPanels();
}
protected void initListPanels()
{
sysListPanelDlvMode.init();
sysListPanelDlvMode.fill();
}
}
L'inizializzazione della classe LILSysListPanel_VendDlvModeAssociation và fatta sottoscrivendo l'evento "Initializing" altrimenti il controllo non viene visualizzato correttamente nella form. Questo vale anche per "SysListPanelRelationTableCallback" usato in precedenza. Si veda come esempio la classe standard SimulationJournalGroupForm_ApplicationSuite_Extension
5) Creiamo la classe EventHandler:
class LILVendParametersFormEH
{
[FormEventHandler(formStr(VendParameters), FormEventType::Initializing)]
public static void VendParameters_OnInitializing(xFormRun sender, FormEventArgs e)
{
FormRun fr = sender as FormRun;
LILSysListPanel_VendDlvModeAssociation sysListPanelDlvMode = LILSysListPanel_VendDlvModeAssociation::newForm(fr, fr.controlId(formControlStr(VendParameters, LILDlvMode)));
fr.parmSysListPanel(sysListPanelDlvMode);
}
}
