Scroll and scrollbars - issues

Hello.

I am currently making a level editor for my game.

I have simplified the capx to only show the editor portion.

You can find it here.

I am currently fighting with the scrolling of content.

I found a thread on scrollbars here (I found another one but it was more flawed)

construct.net/en/forum/construct-2/beginners-questions-19/scrollbar-web-page-111884

And I used the content there and adjusted to my needs and also included a horizontal.

I really tried to figure out the values and adjusted to what's relevant for my project.

I am however struggling with two things. Naturally it all has to do with the calculations...

* Start the capx.

* Scroll far to the max on horizontal and/or vertical bars.

You can see the gray background at the bottom/right. I don't want to scroll onto the gray background. it should stop at the brown edge.

Second problem:

The original capx didn't really have anything to go for the max size of the content?

to showcase:

*Start the capx.

*Click on "NEW" button

* Enter map size width: 14, Height: 63. (the min and the max respectively) and click on OK.

Now try to scroll down as far as you can. You see it will stop before the area is finished.

I use LevelWidth and LevelHeight to set the size of the level area (the workable area) and the TOOLBAR is a "constant" of the Toolbar width.

Somehow I need to work these into the scrolling events.

But sadly I am not best at calculations.

So if you can help me solve these two problems above, I would be thankful!

I will also need to solve the "pan with hand" later on, but it will be a later problem. (Likewise with the dragging while painting/selecting marquee etc)

I don't have any third party addons so I can't open your capx but here is one way to have a scrollable area with scrollbars and hand pan. It clamps to the Scrollwindow to the scrollArea but the scrollwindow has to be smaller than the scrollarea.

In concept you can have multiple scrollable areas. One per window, but the capx would need modifying to handle that.

Oh I forgot about checking if there's addons remaining in.

I will 1. Look through your example and see if I can use it and adapt it.

And if i fail, I will sanitize my capx. I forgot that aspect.

Thank you for your reply, R0j0!

I went back to my own capx and I managed to solve the constraints for the drag range by updating these two events.

Whew!

Now onto the hand tool!
