AW: Widget performance
You could create your custom dropdown menu by using one single project form and some code. The dropdown will display this form. No overhead. Have a look at the type ahead component I published a while ago, you could adapt the concept I use there to build your own dropdown menu. -Ursprüngliche Nachricht- Von: 4D_Tech [mailto:4d_tech-boun...@lists.4d.com] Im Auftrag von Piotr Chabot Stadhouders via 4D_Tech Gesendet: Samstag, 26.

After all, when inserting 100 widget I am in fact inserting 100 subforms.

RE: Listbox header OSX
Hi Miyako, Thanks for your answer. As I understand correctly the only way to get rid of the lines is by changing system appearances in OSX. Gr, Piotr Miyako wrote : "Hello, the Header of a listbox takes after the appearance of a standard menu bar. on Windows 10, the menu bar happens to be white and has no borders and so does the Header. but you can configure system appearances (themes) and that will have an effect on Headers too. as for borders on Mac, you should be able to see that the borders of the Listbox itself can be hidden, in which case the borders of the Header on the sides are also gone. the lines above and below the Header are thinner than what you can define as a line in 4D, I would assume that it originates with the system." > -Oorspronkelijk bericht- > Van: Piotr Chabot Stadhouders [mailto:p.stadhoud...@timeff.com] > Verzonden: vrijdag 25 augustus 2017 9:56 > Aan: 4d_tech@lists.4d.com > Onderwerp: Listbox header OSX > > Hi, > > 4D v16, OSX > > When I set the border line style of a listbox to none OSX still shows a line > above the header.
