How Do I Set the Focus To a Given Control in a DialogInput[] Statement?

Brad Varey

Posted 11 years ago

I have the following code: DialogInput[{name = "", id = ""}, Grid[{{"Name: ", InputField[Dynamic[name], String, FieldHint -> "Enter the name"]}, {"ID: ", InputField[Dynamic[id], String, FieldHint -> "Enter the three-digit ID"]}, {"", Grid[{{Button["OK", DialogReturn[{name, id}], ImageSize -> Automatic], Button["Cancel", DialogReturn[{}], ImageSize -> Automatic]}}]}}], WindowTitle -> "Add New Record"]; When I execute the statement -- either from within a notebook or via code produced in Workbench -- the dialog pops up, but there is no focus on any control, so I have to use the mouse before I can start typing. Is there a way to set the focus to the first InputField[], or, better, any control on the DialogInput[]? Thanks in advance Brad

     InputField[Dynamic[id], String, 
      FieldHint -> "Enter the three-digit ID"]}, {"", 
     Grid[{{Button["OK", DialogReturn[{name, id}], 
         ImageSize -> Automatic], 
        Button["Cancel", DialogReturn[{}], 
         ImageSize -> Automatic]}}]}}], 
  WindowTitle -> "Add New Record"];

This method is undocumented but used in `Input` which sets focus on its field automatically. http://mathematica.stackexchange.com/a/81352/ Moreover it is introduced by WRI quite recently so maybe it will stay. DialogInput[{name = "", id = ""}, Grid[{{"Name: ", InputField[Dynamic[name], String, FieldHint -> "Enter the name"]}, {"ID: ", InputField[Dynamic[id], String, FieldHint -> "Enter the three-digit ID", BoxID -> "fieldWithID"]}, {"", Grid[{{Button["OK", DialogReturn[{name, id}], ImageSize -> Automatic], Button["Cancel", DialogReturn[{}], ImageSize -> Automatic]}}]}}], WindowTitle -> "Add New Record", Initialization :> ( MathLink`CallFrontEnd[ FrontEnd`BoxReferenceFind[ FE`BoxReference[InputNotebook[], {{"fieldWithID"}}, FE`BoxOffset -> {FE`BoxChild[1]}, FE`SearchStart -> "StartFromBeginning"]]] )] If you want to avoid undocumented functions, here is a description of approach based on `SelectionMove`. Probably more stable but not so flexible. http://mathematica.stackexchange.com/a/1463/5478

DialogInput[{name = "", id = ""}, 
 Grid[{{"Name: ",    InputField[Dynamic[name], String,     FieldHint -> "Enter the name"]},
          {"ID: ",    InputField[Dynamic[id], String,    FieldHint -> "Enter the three-digit ID",   
                                             BoxID -> "fieldWithID"]}, 
          {"", 
    Grid[{{Button["OK", DialogReturn[{name, id}],       ImageSize -> Automatic],       Button["Cancel", DialogReturn[{}], 
        ImageSize -> Automatic]}}]}}], 
 WindowTitle -> "Add New Record",
 Initialization :> (
   MathLink`CallFrontEnd[        FrontEnd`BoxReferenceFind[
     FE`BoxReference[InputNotebook[], {{"fieldWithID"}},       FE`BoxOffset -> {FE`BoxChild[1]}, 
      FE`SearchStart -> "StartFromBeginning"]]]
   )]
