Omnis Technical Note TNGI0032Oct 2023

Enhancing your Tool Tips

for Omnis Studio 10.2 or above
Thanks to Christian Müller for providing this tech note

There is a great feature in Omnis Studio that allows you to popup a tooltip that shows some information when the user hovers their mouse over an item, for example, hovering over the cells in a Complex grid.

With the following technique, you can automatically call a function that receives a reference to the row of the data list, and in addition you can use the style() function to give your tooltip a better appearance.

Formatted tool tips

To show how you can create formatted tooltips, I have created a window with a Complex grid. Each field in the grid has the following argument within its $tooltip property using square brackets:

The $getTooltip method receives a reference to the row under the mouse and contains the following code to format the tooltip:

The method uses the style() function to implement certain formatting properties such as adding an icon, and changing the font style and colors of the text.

There is a sample library which demonstrates this technique (compatible with Omnis Studio 11 revision 35659 or above).
