Property that tells if an empty value must be shown next to the items in the value list. |
|
|
Sample var vlist = solutionModel.newValueList('options', JSValueList.CUSTOM_VALUES);
vlist.customValues = "one\ntwo\nthree\nfour";
vlist.addEmptyValue = JSValueList.EMPTY_VALUE_NEVER;
var cmb = form.newComboBox('my_table_text', 10, 10, 100, 20);
cmb.valuelist = vlist; |
|
|
|
|
A string with the elements in the valuelist. The elements can be separated by linefeeds (custom1 custom2), optional with realvalues ((custom1|1 custom2|2)). |
|
|
Sample var vl1 = solutionModel.newValueList("customtext",JSValueList.CUSTOM_VALUES);
vl1.customValues = "customvalue1\ncustomvalue2";
var vl2 = solutionModel.newValueList("customid",JSValueList.CUSTOM_VALUES);
vl2.customValues = "customvalue1|1\ncustomvalue2|2";
var form = solutionModel.newForm("customvaluelistform",controller.getDataSource(),null,true,300,300);
var combo1 = form.newComboBox("scopes.globals.text",10,10,120,20);
combo1.valuelist = vl1;
var combo2 = form.newComboBox("scopes.globals.id",10,60,120,20);
combo2.valuelist = vl2; |

|
Compact representation of the names of the server and table that are used for loading the data from the database. |
|
|
Sample var vlist = solutionModel.newValueList('options', JSValueList.DATABASE_VALUES);

vlist.setDisplayDataProviderIds('parent_table_text');
vlist.setReturnDataProviderIds('parent_table_text'); |

|
|
|
Gets or sets the fallback valuelist. |
|
|
Sample var myValueList = solutionModel.getValueList('myValueListHere')
//get fallback value list
var fallbackValueList = myValueList.fallbackValueList |
|
|
|
|
A global method that provides the data for the valuelist. The global method must provided the data as a JSDataSet.
It is called when the valuelist needs data, it has 3 modes. real and display params both null: return the whole list only display is specified, called by a typeahead, return a filtered list only real value is specified, called when the list doesnt contain the real value for the give record value, this will insert this value into the existing list.
In find mode the record with be the FindRecord which is just like a normal JSRecord (DataRecord) it has the same properties (column/dataproviders) but doesnt have its methods (like isEditing()) |
|
|
Sample var listProvider = solutionModel.newGlobalMethod('globals', 'function getDataSetForValueList(displayValue, realValue, record, valueListName, findMode) {' +
' ' +
'var args = null;' +
'/** @type QBSelect<db:/example_data/employees> */' +
'var query = databaseManager.createSelect('db:/example_data/employees');' +
'/** @type {JSDataSet} */' +
'var result = null;' +
'if (displayValue == null && realValue == null) {' +
' // TODO think about caching this result. can be called often!' +
' // return the complete list' +
' query.result.add(query.columns.firstname.concat(' ').concat(query.columns.lastname)).add(query.columns.employeeid);' +
' result = databaseManager.getDataSetByQuery(query,100);' +
'} else if (displayValue != null) {' +
' // TYPE_AHEAD filter call, return a filtered list' +
' args = [displayValue + "%", displayValue + "%"]' +
' query.result.add(query.columns.firstname.concat(' ').concat(query.columns.lastname)).add(query.columns.employeeid).' +
' root.where.add(query.or.add(query.columns.firstname.lower.like(args[0] + '%')).add(query.columns.lastname.lower.like(args[1] + '%')));' +
' result = databaseManager.getDataSetByQuery(query,100);' +
'} else if (realValue != null) {' +
' // TODO think about caching this result. can be called often!' +
' // real object not found in the current list, return 1 row with display,realvalue that will be added to the current list' +
' // dont return a complete list in this mode because that will be added to the list that is already there' +
' args = [realValue];' +
' query.result.add(query.columns.firstname.concat(' ').concat(query.columns.lastname)).add(query.columns.employeeid).' +
' root.where.add(query.columns.employeeid.eq(args[0]));' +
' result = databaseManager.getDataSetByQuery(query,1);' +
'}' +
'return result;' +
'}');

|
|
|
|
The name of the database table that is used for loading the values when the value list has the type set to database values. |

vlist.useTableFilter = true;
vlist.name = 'two'; |
|
|
|
|
The type of the valuelist. Can be either custom values or database values. |
|
|
Sample var vlist = solutionModel.newValueList('options', JSValueList.CUSTOM_VALUES);
vlist.valueListType = JSValueList.DATABASE_VALUES; // Change the type to database values.
vlist.dataSource = 'db:/example_data/parent_table';
