Added classes to manage simple tabular data of known structure using a popup containing a wxGrid object. BasePicker : Abstract class adding a popup to wxPickerBase styled with a wxTextCtrl. BaseGridPicker : Abstract class adding a wxGrid in the popup. JsonGridPickerCtrl : UI control storing the tabular data in a JSON array. LBoundJsonGridPicker : connect JsonGridPicker to database. LGridJsonCellEditor : use LBoundJsonGridPicker in other wxGrid objects. LGridJsonCellRenderer : render cell JSON data. XmlGridPickerCtrl : UI control storing the tabular data in as XML document. LBoundXmlGridPicker : connect XmlGridPicker to database. LGridXmlCellEditor : grid editor for LBoundXmlGridPicker. LGridXmlCellRenderer : grid renderer for LBoundXmlGridPicker. JsonHelper and XmlHelper : for applications to quickly get intent value from database data.. The structure of managed tabular data : Column 1 : Intent - this is what we want to store/edit. This can be telephone numbers, email addresses, instant messaging addresses... any single line piece of information that can exist many times for one entity (person, company...). Column 2 : Type - A short description of the intent : 'Home, Work, Mobile, Fax, Other...'. It is displayed in a non editable wxComboBox. Column 3 : Preferred - One line of data can be selected as the preferred one. It is not mandatory, but it must be a single choice. Column 4 : Notes - single line notes. Adjust sql scripts and L7.dox. Applied ANSI formatting style to all files. Other changes : Work around a nasty misbehavior. Grid columns edited by a translated combobox expect full string data as cell values. LResultSet::BEData() will report these mapped strings, instead of database real data. LBoundComboBox::IsDirty() will always be true even if the editor is unchanged once created. Simplest workaround : disconnect m_BoundComboBox if unchanged. LGridTextEditor::ProvideFormEditor() : set the form editor's value explicitely.; wxTextCtrl does not interpret data it receives LBoundControl::SetNull must be void. LBoundGrid : Unbind:: instructions should limit to the widget's id, like Bind:: LConnection::GetReturnedKeys should return NULL. LConnection::SetData should return void. Notes : wxJSON must be configured with the same prefix as wxWidgets, here /usr/local/{wxWidgets,wxWidgets-Release}.
