DialogControl service

SFDialogs.DialogControl service

The DialogControl service manages the controls belonging to a dialog defined with the Basic Dialog Editor. Each instance of the current service represents a single control within a dialog box. API;awt.XControl API;awt.XControlModel The focus is set on getting and setting the values displayed by the controls of the dialog box. Formatting is accessible via the XControlModel and XControlView properties. Note that the unique DialogControl.Value property content varies according to the control type. A special attention is given to controls of type tree control. It is easy to populate a tree, either branch by branch, or with a set of branches at once. Populating a tree control can be performed statically or dynamically.
The SFDialogs.DialogControl service is closely related to the SFDialogs.Dialog service.

Service invocation

The DialogControl service is invoked from an existing Dialog service instance through its Controls() method. The dialog must be initiated with the SFDialogs.Dialog service. Dim myDialog As Object, myControl As Object Set myDialog = CreateScriptService("SFDialogs.Dialog", "GlobalScope", myLibrary, DialogName) Set myControl = myDialog.Controls("myTextBox") myControl.Value = "Dialog started at " & Now() myDialog.Execute() ' ... process the controls actual values myDialog.Terminate() from time import localtime, strftime dlg = CreateScriptService('SFDialogs.Dialog', 'GlobalScope', lib_name, dlg_name) text = dlg.Controls('myTextBox') text.Value = "Dialog started at " + strftime("%a, %d %b %Y %H:%M:%S", localtime()) dlg.Execute() # ... process the controls actual values dlg.Terminate() Alternatively a control instance can be retrieved via the SFDialogs.DialogEvent service, providing the dialog was initiated with the Dialog service. DialogEvent returns the SFDialogs.DialogControl class instance that triggered the event. Sub SomeEvent(ByRef poEvent As Object) Dim oControl As Object Set oControl = CreateScriptService("SFDialogs.DialogEvent", poEvent) ' ... End Sub def some_event(event: uno): ctrl = CreateScriptService('SFDialogs.DialogEvent', event) # ... Note that in previous examples, the prefix "SFDialogs." may be omitted.

AddSubNode -------------------------------------------------------------------------------------------------------------------------- DialogControl service;AddSubNode

AddSubNode

Create and return a new node of the tree control as a UNO object subordinate to a parent node. Refer to XMutableTreeNode in Application Programming Interface (API) documentation for detailed information.
This method may be called before displaying the dialog box to build the initial tree. It may also be called from a dialog or control event - using the OnNodeExpanded event - to complete the tree dynamically.

svc.AddSubNode(parentnode: uno, displayvalue: str, opt datavalue: any): uno

parentnode: A node UNO object, of type com.sun.star.awt.tree.XMutableTreeNode. displayvalue: The text appearing in the tree control box.
datavalue: Any value associated with the new node. datavalue may be a string, a number or a date. Omit the argument when not applicable.

%PRODUCTNAME Basic and Python examples pick up current document's myDialog dialog from Standard library. Dim oDlg As Object, myTree As Object, myNode As Object, theRoot As Object Set oDlg = CreateScriptService("Dialog",,, "myDialog") Set myTree = oDlg.Controls("myTreeControl") Set theRoot = myTree.CreateRoot("Tree top") Set myNode = myTree.AddSubNode(theRoot, "A branch ...") dlg = CreateScriptService('SFDialogs.Dialog', None, None, 'myDialog') tree = dlg.Controls('myTreeControl') root = tree.CreateRoot('Tree top') node = tree.AddSubNode(root, 'A branch ...')
AddSubTree -------------------------------------------------------------------------------------------------------------------------- DialogControl service;AddSubTree

AddSubTree

Return True when a subtree, subordinate to a parent node, could be inserted successfully in a tree control. If the parent node had already child nodes before calling this method, the child nodes are erased.

svc.AddSubTree(parentnode: uno, flattree: any, opt withdatavalue: bool): bool

parentnode: A node UNO object, of type com.sun.star.awt.tree.XMutableTreeNode. flattree: a two dimension array sorted on the columns containing the display values. Such an array can be issued by the GetRows method applied on the SFDatabases.Database service. When an array item containing the text to be displayed is Empty or Null, no new subnode is created and the remainder of the row is skipped. Flat tree >>>> Resulting subtree A1 B1 C1 |__ A1 A1 B1 C2 |__ B1 A1 B2 C3 |__ C1 A2 B3 C4 |__ C2 A2 B3 C5 |__ B2 A3 B4 C6 |__ C3 |__ A2 |__ B3 |__ C4 |__ C5 |__ A3 |__ B4 |__ C6 withdatavalue: When False default value is used, every column of flattree contains the text to be displayed in the tree control. When True, the texts to be displayed (displayvalue) are in columns 0, 2, 4, ... while the data values (datavalue) are in columns 1, 3, 5, ...

Dim myTree As Object, theRoot As Object, oDb As Object, vData As Variant Set myTree = myDialog.Controls("myTreeControl") Set theRoot = myTree.CreateRoot("By product category") Set oDb = CreateScriptService("SFDatabases.Database", "/home/.../mydatabase.odb") vData = oDb.GetRows("SELECT [Category].[Name], [Category].[ID], [Product].[Name], [Product].[ID] " _ & "FROM [Category], [Product] WHERE [Product].[CategoryID] = [Category].[ID] " _ & "ORDER BY [Category].[Name], [Product].[Name]") myTree.AddSubTree(theRoot, vData, WithDataValue := True) SQL_STMT = "SELECT [Category].[Name], [Category].[ID], [Product].[Name], [Product].[ID] \ FROM [Category], [Product] WHERE [Product].[CategoryID] = [Category].[ID] \ ORDER BY [Category].[Name], [Product].[Name]" tree = dlg.Controls('myTreeControl') root = tree.CreateRoot('By Product category') db = CreateScriptService('SFDatabases.Database', '/home/.../mydatabase.odb') sub_tree = db.GetRows(SQL_STMT) tree.AddSubTree(root, sub_tree, withdatavalue=True)
CreateRoot -------------------------------------------------------------------------------------------------------------------------- DialogControl service;CreateRoot

CreateRoot

Returns a new root node of the tree control, as a node UNO object of type com.sun.star.awt.tree.XMutableTreeNode. The new tree root is inserted below pre-existing root nodes. This method may be called before displaying the dialog box to build the initial tree. It may also be called from a dialog or control event to complete the tree dynamically.

svc.CreateRoot(displayvalue: str, opt datavalue: any): uno

displayvalue: The text appearing in the tree control box.

Dim myTree As Object, myNode As Object Set myTree = myDialog.Controls("myTreeControl") Set myNode = myTree.CreateRoot("Tree starts here ...") tree = dlg.Controls('myTreeControl') node = tree.CreateRoot('Tree starts here ...')
FindNode -------------------------------------------------------------------------------------------------------------------------- DialogControl service;FindNode

FindNode

Traverses the tree and finds recursively, starting from the root, a node meeting some criteria. Either - 1 match is enough - having its display value matching displayvalue pattern or having its data value equal to datavalue. The comparisons may be or not case-sensitive. The first matching occurrence is returned as a node UNO object of type com.sun.star.awt.tree.XMutableTreeNode. When not found, the method returns Nothing, to be tested with the IsNull() builtin function. This method may be called before displaying the dialog box to build the initial tree. It may also be called from a dialog or control event.

svc.FindNode(displayvalue: str = '', opt datavalue: any, casesensitive = False): uno

One argument out of displayvalue or datavalue must be specified. If both present, one match is sufficient to select the node. displayvalue: The pattern to be matched. Refer to SF_String.IsLike() method for the list of possible wildcards. When equal to the zero-length string (default), this display value is not searched for. casesensitive: Default value is False

Dim myTree As Object, myNode As Object Set myTree = myDialog.Controls("myTreeControl") Set myNode = myTree.FindNode("*Sophie*", CaseSensitive := True) tree = dlg.Controls('myTreeControl') node = FindNode('*Sophie*', casesensitive=True) if node is None: # ...
SetFocus -------------------------------------------------------------------------------------------------------------------------- DialogControl service;SetFocus

SetFocus

Set the focus on the control. Return True if focusing was successful. This method is often called from a dialog or control event.

svc.SetFocus(): bool

Dim oControl As Object Set oDlg = CreateScriptService("SFDialogs.Dialog",,, "myDialog") Set oControl = oDlg.Controls("thisControl") oControl.SetFocus() dlg = CreateScriptService('Dialog', None, None, 'myDialog') ctrl = dlg.Controls('thisControl') ctrl.SetFocus()
WriteLine -------------------------------------------------------------------------------------------------------------------------- DialogControl service;WriteLine

WriteLine

Add a new line at the end of a multiline text field. A newline character will be inserted when appropriate. The method returns True when successful. An error is raised if the actual control is not of the type TextField or is not multiline.

svc.WriteLine(opt line: str): bool oControl.WriteLine([Line As String]) As Boolean

Line: The string to insert. Default is an empty line.

Dim oDlg As Object, oControl As Object Set oDlg = CreateScriptService("SFDialogs.Dialog",,, "myDialog") Set oControl = oDlg.Controls("thisControl") oControl.WriteLine("a new line") dlg = CreateScriptService('SFDialogs.Dialog', None, None, 'myDialog') ctrl = dlg.Controls('thisControl') ctr.WriteLine("a new line")
