Hi, Based on the tip op Chip (sounds nice😊), I have created a function that can be used in the "On Column Resize" event:
C_TEXT($listbox;$1) C_BOOLEAN($mouse_in_listbox;$0) $listbox:=$1 C_BOOLEAN($mouse_in_listbox) GET MOUSE($mouseX;$mouseY;$mouseButton) OBJECT GET COORDINATES(*;$listbox;$l;$t;$r;$b) If ($mouseX>=$l) & ($mouseX<=$r) & ($mouseY>=$t) & ($mouseY<=$b) $mouse_in_listbox:=True Else $mouse_in_listbox:=False End if $0:=$mouse_in_listbox > -----Oorspronkelijk bericht----- > Van: Piotr Chabot Stadhouders [mailto:p.stadhoud...@timeff.com] > Verzonden: vrijdag 5 januari 2018 10:06 > Aan: 4D iNug Technical <4d_tech@lists.4d.com> > Onderwerp: RE: On Column Resize event > > Hi Chip, Miyako, > > @Chip : > Thanks, this is a nice tip! > But don't you agree it should be easier, and 4D should have thought about > this, > and implement it another way? > > @Miyako : > I know there is a new auto-resize feature, but this works not as how we want > it > In fact we have implemented an auto-resize feature ourselves, and this is > exactly why we have a problem now When a user resizes a column we > determine the ratio's of the column widths (We do this in the "On Column > Resize" event) When resizing the listbox (by resizing the window for example) > in the "On Resize" event we set the widths proportionally based on the ratio's > calculated earlier > > Gr, > > Piotr > > > -----Oorspronkelijk bericht----- > > Van: Chip Scheide [mailto:4d_o...@pghrepository.org] > > Verzonden: donderdag 4 januari 2018 18:22 > > Aan: 4D iNug Technical <4d_tech@lists.4d.com> > > CC: Piotr Chabot Stadhouders <p.stadhoud...@timeff.com> > > Onderwerp: Re: On Column Resize event > > > > Piotr, > > 'On Timer' can be used to limit execution of the On Column Resize event. > > I have seen a similar problem with other resizing situations. > > > > Basically - you start a timer for a .5 second or so, then On timer > > executes the code. > > This reduces the number of times the code runs. > > > > For differentiating between manual resizing of a column vs auto > > resizing via a window resize, you could try setting a flag.
