Question

I’m using OpenEdge ABL / Progress 4GL. I have a browser widget populated with rows. When I left click a row the row is highlighted and that row is now in focus. I want when I right click on a different row for progress to perform a “left click” (to move the focus to the row that was right clicked on) then do the right click.

Answer 1

I already answered this question here : How in OpenEdge ABL / Progress 4GL do I find the row id of a row that is right clicked in a browser.

I’m not sure what the policy is with this duplicate question, but I’m repeating my answer here, I hope it’s OK.

I had a similar situation; I wanted to respond to the mouse’s Right-click in a browse. Right-clicking does not select the row you’re clicking on, so I had to programmatically figure out which row it was. The coding below determines which row you clicked on and selects it. I am afraid it really is this complicated.

This goes in the MOUSE-MENU-DOWN event of the browse:

DEFINE VARIABLE iRowHeight   AS INTEGER     NO-UNDO.
DEFINE VARIABLE iLastY       AS INTEGER     NO-UNDO.
DEFINE VARIABLE iRow         AS INTEGER     NO-UNDO.
DEFINE VARIABLE hCell        AS HANDLE      NO-UNDO.
DEFINE VARIABLE iTopRowY     AS INTEGER     NO-UNDO.

/* See if there are ANY rows in view... */
IF SELF:NUM-ITERATIONS = 0 THEN 
DO:
   /* No rows, the user clicked on an empty browse widget */
   RETURN NO-APPLY. 
END.

/* We don't know which row was clicked on, we have to calculate it from the mouse coordinates and the row heights. No really. */
SELF:SELECT-ROW(1).               /* Select the first row so we can get the first cell. */
hCell      = SELF:FIRST-COLUMN.   /* Get the first cell so we can get the Y coord of the first row, and the height of cells. */
iTopRowY   = hCell:Y - 1.         /* The Y coord of the top of the top row relative to the browse widget. Had to subtract 1 pixel to get it accurate. */
iRowHeight = hCell:HEIGHT-PIXELS. /* SELF:ROW-HEIGHT-PIXELS is not the same as hCell:HEIGHT-PIXELS for some reason */
iLastY     = LAST-EVENT:Y.        /* The Y position of the mouse event (relative to the browse widget) */

/* calculate which row was clicked. Truncate so that it doesn't round clicks past the middle of the row up to the next row. */
iRow       = 1 + TRUNCATE((iLastY - iTopRowY) / iRowHeight, 0). 

IF iRow > 0 AND iRow <= SELF:NUM-ITERATIONS THEN 
DO:
  /* The user clicked on a populated row */
  Your coding here, for example:
  SELF:SELECT-ROW(iRow).
END.
ELSE DO:
  /* The click was on an empty row. */
  SELF:DESELECT-ROWS().
  RETURN NO-APPLY.
END.

I hope this helps.
