BCGSuite for MFC full changelog

Implemented built-in support for the Windows light and dark themes (see screenshot): the virtual theme BCGP_VISUAL_THEME_SYSTEM was added to the CBCGPWinApp::BCGP_VISUAL_THEME enumerator. By default, the library activates the MS Office 2024 white theme when the Windows app mode is set to light and the MS Office 2024 black theme when the mode is set to dark; however, you can specify your preferred themes by calling the new CBCGPWinApp method SetSystemVisualThemeOptions (see BCGPVisualStudioGUIDemo, where we show the system light theme is associated with the Visual Studio 2026 light and dark theme with Visual Studio 2026 dark). This theme was added to most examples and samples and Application Wizard-generated source code. If you wish to add this theme to your UI, please add a new constant BCGP_THEMES_LIST_SYSTEM to the list of themes passed to the CBCGPWinApp method SetApplicationLookMenu, and the "Use System Setting" item will be added to the "Theme" menu (see screenshot).
Ribbon Bar:
Added the collapsed panel icon style. Call a new method of the CBCGPRibbonBar class SetPanelDefaultButtonIconStyle to specify the icon style (visual manager-specific, always simplified or original) and GetPanelDefaultButtonIconStyle to obtain this style.
CBCGPRibbonCustomizationOptions::m_strCustomizationFilePath specifies the initial folder for the import/export file dialog. If this member is empty (by default), the current folder will be used.
A new class, CBCGPRibbonColorComboBox, implements the ribbon combo box with the color items (see screenshot). You can add accent, standard (Web), system or custom colors. The RibbonGadgets sample demonstrates this addition.
Toolbars and Menus:
CBCGPExplorerToolBar: implemented the ability to specify the address bar margins. The method EnableAddressBar has a new, optional parameter, 'rectAddressBarMargins.'
A new class CBCGPToolbarColorComboBoxButton, implements the toolbar combo box with the color items (see screenshot). You

Ribbon Bar:
CBCGPRibbonCustomizationOptions: A new member m_bAddSubItemsToTreePanel specifies whether Ribbon control sub-items should be added to the panel node of the customization tree (TRUE by default).
CBCGPRibbonBar::ShowBackstageView has a new, optional parameter, nSubPage. This parameter specifies a subpage to activate (CBCGPRibbonBackstageViewItemPropertySheet only).
CBCGPRibbonColorButton: Improved behavior of the selected color; when SetSelectedColor was called with parameter CLR_NONE, no color is selected now on the dropped-down color palette.
CBCGPRibbonBar: A new virtual method GetExportedFileDefaultName allows you to specify the customization data file default name. By default, this name is the same as the application name.
Toolbars and Menus:
Improved toolbar editing: now, you can specify the common attributes, such as image lists or toolbar names, in the Toolbar Editor, and these attributes will be automatically loaded by the framework (see screenshot).
Added support for the menu item data in the menu bar import and export methods (CBCGPToolbarMenuButton::CreateFromMenu and CBCGPToolbarMenuButton::CreateMenu).
Dialogs and Forms:
CBCGPMessageBox: A new static member m_nTextCalculationStep specifies the text layout calculation tolerance (in pixels, 10 by default). Specify a larger value if you have message boxes with long texts to optimize the dialog initialization time.
Improved appearance of dialog controls when the user specified the custom Windows text size. All controls have the same font size as the parent dialog font.
MDI Windows and Tabs:
CBCGPMDITabParams: A new member m_bBalancedGroupLayout specifies whether the MDI tabbed groups have the same size after creating a new tabbed group. Please take a look at the MDITabsDemo sample to see this new feature in action.
CBCGPAppOptions: A new member m_bAutoChangeMDITabsStyle specifies whether MDI tabs style should be changed upon the visual theme changing (e.g., in Office 2007-2010 themes, MDI tabs ar
