Wt

Hi,

like you said, sometimes it does use the full height. And I noticed that when it doesn't fit, a scrollbar shows up on the entire page. So if you keep your cursor on the tooltip the scrolling actually works.

Only question is why it is sometimes not working ... I will look into this further.

Okay, my example is not specific enough to the use case we have in our app.
In our app the page itself cant be resized like that to allow scrolling the tooltip like that.
I know such huge tooltips are rather crazy, but in our case it would be great if the tooltip itself could be scrolled if it does not fit.
With the browse development tools, I was able to manipulate the tooltip to scroll, but I did see no way customize this in the app.

If I remember correctly "fitToWindow" in Wt.js is used to place the tooltip, but like you said it now occured to me it must make the page scrollable.

If you like I can provide you with a better example, but maybe this does not fit this issue any more.

I was actually playing with an implementation to have the tooltip scroll rather than the page. Right now it is indeed fitToWindow that calculates the position of the tooltip, but I might change it so the tooltip is simply placed with a CSS position: fixed. This seems much more straigthforward. A consequence is that the page will no longer scroll, so if I go with this, the tooltip will have to become scrollable.

If you provide another example, I will be happy to use it during testing :)

Sounds good!
I tried the initial example provided in this issue again, I cant get it to scroll. So it seems it shows our use case pretty good.
If you can get it to scroll without modifying the code, I dont know how you do it.

If I remove the WVBoxLayout and the SizeAwareContainer, and add the WPushButtons to the root() then I see the scrolling of the full page.
