Is it possible to make a test-app for this issue?

Problem still exists in AC 12.05

I'm sorry, I can't compile the demo. The 'Common' doesn't exists.

You probably already found the correct version:

You can remove 1 topic, I think…

The topic you're referring to is an offer to include the code into one of the upcoming releases of AC.

The same code is used here to show a bug in the TsWebBrowser component.

So both topics serve their own purpose.

Thank you

I can suggest you to hide this control in the document body style:

Code:

I can't remove this scroll by delphi code, unfortunately, because it's drawn in the document and I have no idea how to do it currently.

In principle, this is a good solution, but the TsWebBrowser component will show a horizontal scroll bar if the HTML text does not fit the window.

It should not do that, in fact it should almost never do that, because the text should be wrapped.

It's almost impossible to get rid of the horizontal scroll bar.

To illustrate, this is the same demo project, but with the suggested addition of disabling the vertical scroll bar:

Try to get rid of the horizontal scroll bar.

Setting SkinData.HorzScrollData.ScrollWidth to 0 will do the trick. But that would disable the horizontal scroll bar for all content.

Thank you for the demo.

I know how to remove a scrollbar, but I don't know When I must do that.

That's the problem, I can't catch event when visivility of scrollbar is changed.

What's the best way to remove the scrollbar? Maybe I can do it myself?

Try this line:

Code:

WebBrowser.OleObject.Document.Body.Style.OverflowY := 'hidden';

Just an observation:

Every time a webpage does not fit the window, a nicely themed vertical scrollbar appears. Apparently AC is able to find out when to draw this scrollbar. Then if the page does fit the window, the themed scrollbar disappears. And it comes back again when the page does not fit the window.

Now you're saying that you do not know when to remove the standard scrollbar. But in a way AC does this already. Because when you remove the styled scrollbar, that's also the time to remove the standard vertical scrollbar.

Just a thought.

Hello!

I will try to do it, but my solution for hiding of std scrolls is not universal, seems.

Have you checked this code more?

I've done better than that, I've found a good solution to this.

Have a look at this article. It comes complete with a demo program. Its principle is to host the webbrowser in a specially crafted IDocHostUIHandler interface. By doing so, apparently you can show and hide the vertical scroll bar at will.

Thank you for a link

Do you have pages examples which I can test? Where scrollbar is shown as not skinned.

Thanks Serge

It works like a charm, except for one problem:

If the web window is resized, making it smaller and making the AC scroll bar appear, there is no redrawing of the web page, and that causes a text clipping:

[attachment=8617:WebPage Unclipped.jpg]

goes to:

[attachment=8618:WebPage Cllipped.jpg]

Look at the upper right: text falls off the window.

The other way around (going from a scrolled window to a full one) the page is redrawn correctly. So it is probably a simple oversight.
