Dialog service

SFDialogs.Dialog service

The Dialog service contributes to the management of dialogs created with the Basic Dialog Editor. Each instance of the current class represents a single dialog box displayed to the user.

A dialog box can be displayed in modal or in non-modal modes. In modal mode, the box is displayed and the execution of the macro process is suspended until one of the OK or Cancel buttons is pressed. In the meantime, user actions executed on the box can trigger specific actions. In non-modal mode, the dialog box is "floating" on the user desktop and the execution of the macro process continues normally. A non-modal dialog closes when it is terminated with the Terminate() method or when the %PRODUCTNAME session ends. The window close button is inactive in non-modal dialogs. A dialog box disappears from memory after its explicit termination. The SFDialogs.Dialog service is closely related to the SFDialogs.DialogControl service.

Service invocation and usage

Before using the Dialog service the ScriptForge library needs to be loaded or imported:

The Dialog service is invoked through the CreateScriptService method. It requires three positional arguments to specify the dialog box to activate: Container: "GlobalScope" for preinstalled libraries or a window name as defined by ScriptForge.UI service. Empty string "" default value stands for the current document. Library: The case-sensitive name of a library contained in the container. Default value is "Standard". DialogName: A case-sensitive string designating the dialog. Below %PRODUCTNAME Basic and Python examples are displaying the dlgConsole dialog that belongs to ScriptForge shared library: Dim oDlg As Object, lButton As Long Dim Container As String, Library As String, DialogName As String Set oDlg = CreateScriptService("SFDialogs.Dialog", "GlobalScope", "ScriptForge", "dlgConsole") '... controls initialization goes here... lButton = oDlg.Execute() 'Default mode = Modal If lButton = oDlg.OKBUTTON Then '... Process controls and do what is needed here End If oDlg.Terminate() Or using Python: dlg = CreateScriptService('SFDialogs.Dialog', 'GlobalScope', 'ScriptForge', 'dlgConsole') # ... controls initialization goes here... rc = dlg.Execute() # Default mode is Modal if rc == dlg.OKBUTTON: # ... Process controls and do what is needed here dlg.Terminate() Alternatively a Dialog instance can be retrieved via the SFDialogs.DialogEvent service, providing that the dialog was initiated with the Dialog service. DialogEvent returns the SFDialogs.Dialog service instance that triggered the event. Sub SomeEvent(ByRef poEvent As Object) Dim oDlg As Object Set oDlg = CreateScriptService("SFDialogs.DialogEvent", poEvent) End Sub with Python: def some_event(event: uno): dlg = CreateScriptService("SFDialogs.DialogEvent", event) Note that in previous examples, the prefix "SFDialogs." may be omitted when deemed appropriate.

Activate -------------------------------------------------------------------------------------------------------------------------- Dialog service;Activate

Activate

Set the focus on the current Dialog instance. Return True if focusing was successful. This method is called from a dialog or control event, or when a dialog is displayed in non-modal mode.

svc.Activate(): bool

Dim oDlg As Object Set oDlg = CreateScriptService(,, "myDialog") oDlg.Execute() ' ... oDlg.Activate() Python and %PRODUCTNAME Basic examples both assume that the dialog is stored in current document's Standard library. dlg = CreateScriptService(,,'myDialog') dlg.Execute() # ... dlg.Activate()

Center -------------------------------------------------------------------------------------------------------------------------- Dialog service;Center

Center

Centers the current dialog instance in the middle of a parent window. Without arguments, the method centers the dialog in the middle of the current window. Returns True when successful.

svc.Center(opt Parent: obj): bool

Parent: An optional object that can be either … a ScriptForge dialog object a ScriptForge document (Calc, Base, ...) object

Sub TriggerEvent(oEvent As Object) Dim oDialog1 As Object, oDialog2 As Object, lExec As Long Set oDialog1 = CreateScriptService("DialogEvent", oEvent) ' The dialog that caused the event Set oDialog2 = CreateScriptService("Dialog", ...) ' Open a second dialog oDialog2.Center(oDialog1) lExec = oDialog2.Execute() Select Case lExec ... End Sub

def triggerEvent(event: uno): dlg1 = CreateScriptService('DialogEvent.Dialog', event) # The dialog having caused the event dlg2 = CreateScriptService('Dialog', ...) # Open a second dialog dlg2.Center(dlg1) rc = dlg2.Execute() if rc is False: # ...

Controls -------------------------------------------------------------------------------------------------------------------------- Dialog service;Controls

Controls

Return either: the list of the controls contained in the dialog a DialogControl class instance based on its name

svc.Controls(): str[0..*] svc.Controls(controlname: str): svc

ControlName : A valid control name as a case-sensitive string. If absent, the list of control names is returned as a zero-based array.

Dim myDialog As Object, myList As Variant, myControl As Object Set myDialog = CreateScriptService("SFDialogs.Dialog", , "Standard", "Dialog1") myList = myDialog.Controls() Set myControl = myDialog.Controls("myTextBox") dlg = CreateScriptService('SFDialogs.Dialog','', 'Standard', 'Dialog1') ctrls = dlg.Controls() ctrl = dlg.Controls('myTextBox')

EndExecute -------------------------------------------------------------------------------------------------------------------------- Dialog service;EndExecute

EndExecute

Ends the display of a modal dialog and gives back the argument as return value for the current Execute() running action. EndExecute() is usually contained in the processing of a macro triggered by a dialog or control event.

svc.EndExecute(returnvalue: int)

returnvalue: The value passed to the running Execute() method.

Using %PRODUCTNAME Basic: Sub OnEvent(poEvent As com.sun.star.lang.EventObject) Dim oDlg As Object Set oDlg = CreateScriptService("SFDialogs.DialogEvent", poEvent) oDlg.EndExecute(ReturnValue := 25) End Sub Using Python: from com.sun.star.lang import EventObject def on_event(event: EventObject): dlg = CreateScriptService("SFDialogs.DialogEvent", event) dlg.EndExecute(25) Above com.sun.star.lang.EventObject mentions are optional. Such annotations help identify %PRODUCTNAME Application Programming Interface (API).

Execute -------------------------------------------------------------------------------------------------------------------------- Dialog service;Execute

Execute

Display the dialog box and, when modal, wait for its termination by the user. The returned value is either: 0 : Cancel button pressed 1 : OK button pressed Otherwise the dialog stopped with an EndExecute() statement issued by a dialog or control event For non-modal dialog boxes the method always returns 0 and the execution of the macro continues.

svc.Execute(modal: bool = True): int

modal: False when non-modal dialog. Default = True.

In this Basic example myDialog dialog is stored in current document's Standard library. Dim oDlg As Object, lReturn As Long Set oDlg = CreateScriptService("SFDialogs.Dialog", , , "myDialog") lReturn = oDlg.Execute(Modal := False) Select Case lReturn ' ... End Select This Python code displays DlgConvert modal dialog from Euro shared Basic library. dlg = CreateScriptService("SFDialogs.Dialog", 'GlobalScope', 'Euro', "DlgConvert") rc = dlg.Execute() if rc == dlg.CANCELBUTTON: # ...

GetTextsFromL10N -------------------------------------------------------------------------------------------------------------------------- Dialog service;GetTextsFromL10N

GetTextsFromL10N

Replaces all fixed text strings in a dialog by their translated versions based on a L10N service instance. This method translates the following strings:

The method returns True if successful. To create a list of translatable strings in a dialog use the AddTextsFromDialog method from the L10N service.

svc.GetTextsFromL10N(l10n: svc): bool

l10n: A L10N service instance from which translated strings will be retrieved.

The following example loads translated strings and applies them to the dialog "MyDialog".

oDlg = CreateScriptService("Dialog", "GlobalScope", "Standard", "MyDialog") myPO = CreateScriptService("L10N", "/home/user/po_files/") oDlg.GetTextsFromL10N(myPO) oDlg.Execute()

dlg = CreateScriptService("Dialog", "GlobalScope", "Standard", "MyDialog") myPO = CreateScriptService("L10N", "/home/user/po_files/") dlg.GetTextsFromL10N(myPO) dlg.Execute() Read the L10N service help page to learn more about how PO and POT files are handled.

Resize -------------------------------------------------------------------------------------------------------------------------- Dialog service;Resize

Resize

Moves the topleft corner of a dialog to new coordinates and/or modify its dimensions. All distances are expressed in 1/100 mm. Without arguments, the method resets the initial dimensions. Return True if the resize was successful.

svc.Resize(opt Left: num, opt Top: num, opt Width: num, opt Height: num): bool

Left: the horizontal distance from the top-left corner Top: the vertical distance from the top-left corner Width: the width of the rectangle containing the dialog Height: the height of the rectangle containing the dialog Negative or missing arguments are left unchanged

oDialog.Resize(1000, 2000, Height := 6000) ' Width is not changed

With Python: oDialog.Resize(1000, 2000, Height = 6000) # Width is not changed

Terminate -------------------------------------------------------------------------------------------------------------------------- Dialog service;Terminate

Terminate

Terminate the Dialog service for the current instance. Return True if the termination was successful.

svc.Terminate(): bool

Below Basic and Python examples open DlgConsole and dlgTrace non-modal dialogs. They are respectively stored in ScriptForge and Access2Base shared libraries. Dialog close buttons are disabled and explicit termination is performed at the end of a running process. In this example a button in DlgConsole is substituting inhibited window closing:

oDlg = CreateScriptService("SFDialogs.Dialog","GlobalScope","ScriptForge","DlgConsole") oDlg.Execute(modal:=False) Wait 5000 oDlg.Terminate() With Python:

from time import sleep dlg = CreateScriptService('SFDialogs.Dialog',"GlobalScope",'Access2Base',"dlgTrace") dlg.Execute(modal=False) sleep 5 dlg.Terminate()
