Limitations of GBC
This page lists the limitations of the Genero Browser Client (GBC) when compared with Genero Desktop Client (GDC).
Drag and Drop
You cannot drag an item from the desktop onto a Genero DISPLAY ARRAY.
Dynamic widget update
- Button with style attribute
buttonType
- CheckBox with style attribute
customWidget
- ScrollGrid with style attribute
customWidget
- Table with style attribute
tableType
This applies to the widgets defined in a GBC customization, when you customize a widget and register it. For example:
cls.WidgetFactory.registerBuilder('MyWidget[attributeName=attributeValue]', cls.MyWidget)
Once the widget has been displayed, you cannot change these style attributes at runtime.
For more information on style attributes for widgets, see the Style attributes reference topics in the Genero Business Development Language User Guide.
Hot key support
When using the Genero Browser Client, some hot key combinations are not supported by specific browsers; they are trapped by the browser. The behavior is not consistent between the available browsers, and Four Js is unable to provide accurate and up-to-date information regarding hot key support for each supported browser.
To make an action available when a hot key combination is not supported, you must make the action visible. For example, add the action to the action panel to allow the user to click a button
Mobile screen operations
When using a mobile device, the application reacts to touch events (finger interactions) instead of mouse clicks.
- Access the context menu with a long tap, where a tap is a finger press. For example, to display a context menu for a table column header, press on the table column header for two seconds.
- To zoom into a page, use two fingers to pinch in on the screen. To zoom out of a page, use two fingers to pinch out on the screen.
- A double tap corresponds to a doubleclick. For example, if you double tap on a row, the row action will be executed. Double tap will not zoom a page.
Windows
In GDC-Native (used in GDC 3.20 or earlier), each new window opened in its own window container.
In GBC (and front ends using Universal Rendering), all windows open in the same container and the user sees the window that is on top of the stack. The user can navigate through the windows using the window list. For further details, see View stacked windows.
