Can I Enable Mouse Wheel Scrolling With The Text Box Control? Primary Software: LabVIEW Development Systems>>Full Development SystemPrimary Software Version: 1.0 Primary Software Fixed Version: N/A Secondary Software: N/A
Problem: I would like to be able to scroll through my Text Box control with the mouse wheel. Is that feature available? Solution: There is not a native feature in LabVIEW to allow for mouse wheel scrolling in the Text Box control. To use this feature, you will need to either program this capability or use the .NET RichTextBox control. The attached example demonstrates how to build a simple scrolling mechanism to enable text box scrolling by using the mouse wheel. This enables the LabVIEW Text Box control to be used instead of the RichTextBox .NET control. The Aquire Input Data.vi captures the mouse wheel position and adjusts the text box scroll position based on the mouse input. The event structure allows the scrolling to occur only when the mouse is over the text box. It also disables scrolling if the user selects the vertical scroll bar to avoid undesirable behavior.
