How to programmatically determine if a bookmark is set for a given line number?

Paul Baker

Is there a way to programmatically set or clear a bookmark? I don’t want to toggle the bookmark. I want to set it if it is not already set.

I have found these message types.

    #define    IDM_SEARCH_TOGGLE_BOOKMARK      (IDM_SEARCH + 5)
    #define    IDM_SEARCH_NEXT_BOOKMARK        (IDM_SEARCH + 6)
    #define    IDM_SEARCH_PREV_BOOKMARK        (IDM_SEARCH + 7)
    #define    IDM_SEARCH_CLEAR_BOOKMARKS      (IDM_SEARCH + 8)

I want to check if a bookmark is set for the current line. If it is, then no additional action needed, if not set then I want to set it.

Is this possible?

Thank You!
Paul

Of course. :-)

“Markers” are a Scintilla function, so I’ll refer you to Scintilla docs for markers HERE.

N++ uses marker ID 20 for bookmarks.
You can search the N++ source code for MARK_BOOKMARK to see some implementation.

Thank you Alan. Everyone on this forum is so helpful. I’ll check out the doc and look for the implementations.

The c# template I am using had these already defined… Not sure how I missed this. But thanks again!

/// <summary>Add a marker to a line, returning an ID which can be used to find or delete the marker. (Scintilla feature 2043)</summary>
        int MarkerAdd(int line, int markerNumber);

        /// <summary>Delete a marker from a line. (Scintilla feature 2044)</summary>
        void MarkerDelete(int line, int markerNumber);

        /// <summary>Delete all markers with a particular number from all lines. (Scintilla feature 2045)</summary>
        void MarkerDeleteAll(int markerNumber);

        /// <summary>Get a bit mask of all the markers set on a line. (Scintilla feature 2046)</summary>
        int MarkerGet(int line);
