Oracle APEX: Tooltip on cell of the report - oracle-apex

Question

I have an APEX tabular form, all columns of which are standard report columns.
Is it possible to display a tooltip on mouse over of a particular cell of the report?

Answer 1

In the report column attributes look for the region named Column Formatting. Inside this section is a text box for an "HTML Expression". Here you can add html to the report column contents e.g., <span title="My tooltip text">#COLUMN_NAME#</span>
The tooltip text could be from another column, you would just replace the contents of the title attribute with the column name surrounded by hashes.

Answer 2

SOLUTION 1:
If your record needs to be editable then this solution works:
Under column attributes go to LINK
For Target: Type - URL and URL is just a hashtag
URL: #
Link Text: &COLUMN_NAME.
Link Attributes: title="&COLUMN_NAME." class="column_name_class"
Then in your inline CSS add the following
.column_name_class{
text-decoration: none !important;
}
Solution one I definitely prefer. But here is solution 2 anyways.
SOLUTION 2:
See here for the solution on JSDoc: Widget Grid
You can also initialize the grid with the tooltip option specified.
function( options ) {
options.defaultGridViewOptions = {
tooltip: {
content: function( callback, model, recordMeta, colMeta, columnDef ) {
var text;
// calculate the tooltip text
return text;
}
}
};
return options;
}
} );
Calculating the tooltip :
config.defaultGridViewOptions = {
tooltip: {
content: function( callback, model, recordMeta, colMeta, columnDef ) {
return model.getValue( recordMeta.record, "COLUMN_NAME");
}
}
}
