Hi. General flow is correct, but GTK+ does offer some functionality that may come handy in your case. (I'm commenting in a rather strange succession because Richard top-posted his reply). > unless gtk is now providing direct access to tooltip style pop-ups, you must create it yourself GTK+ does offer access to tooltips in various ways: you can simply set text or markup; you can insert custom content into tooltip; or you can create your own window and present it as tooltip. > meaning that you must create and manage your own borderless top-level window This is not needed anymore. > whose location must be explicitly specified to be placed onto the screen > calculation of the window location coordinates must access the root-window where to the tooltip is to be located on top of, and > since you don't have access to the size of the WM's borders on the root window, a little "guessing" as to the WM's size must be taken into account If you connect to GtkWidget::query-tooltip signal, coordinates are already provided, so I think most of this stuff is not needed now. >> A textview shows help text with many 'technical' words that users may not know or remember. I would like a tooltip text with a short explanation to pop up when a user hovers the cursor over a technical phrase. There is a lookup table from technical phrases to explanations. I am thinking about using the mouse move event to get x,y then getting the technical phrase from x,y, then looking up the explanation and outputting the tooltip text. Don't use movement events to monitor your position. Simply set text view's "has-tooltip" property to "TRUE" and connect handler to "query-tooltip" signal. Use coordinates provided by callback to find the word that cursor hovers over and then do the lookup. I think things should be relatively simple.
