You're absolutely right.

 

OK so I've created a small codepen to try to explain it better.

 

So in the following codepen if you try to drag the rectangle you can see it will be bound to the limits of the grid.

 

The problem is when you move it, for instance, to 2/3 to the right of the grid, I would like the rectangle not to be able to expand to outside of the grid.

 

The rectangle is bound to the "container" grid. But I would like to define the bounds with a {minX, maxX} so I can define minimum size. By doing this I've not been able to restrict the growth of the rectangle to always be inside the grid, independently of its position

 

Makes sense?

hugonoro,

 

Did you try feeding the $container as the bounds for your handler element? It seems to achieve your desired behaviour (although if you push it against the corner it does go one pixel over but, surely you can mask that out, right?);

 

Alter this:

Draggable.create(handle, {
    type:"x,y",
    bounds: { minX: 0, minY: 0, maxX: $container.width(), maxY: $container.height },

To this:

  Draggable.create(handle, {
    type: "x,y",
    bounds: $container,

I did, the problem with that is that I don't want the handle to move to the left of the element otherwise it will make the element disappear. That's why I'm struggling with this, from the beginning. I need to be able to define a minX So I can never allow it to be smaller than a specified size. The whole Idea is never let the rectangle be smaller than a specific size. Otherwise, yes, your suggestion would solve it :)

Thanks  swampthang and OSUblake.

 

I combined two pen's:

However, the svg handle does not work. Therefore, I attached the file here.

You can resize using the bottom right corner, although the icon is not visible.

As you can see both the dragging and resizing behavior is erratic. What did I do wrong?

now that I looked more carefully, the pen of swampthang is fantastic!: I just need to change the dimensions and some parameters. Although that is not very simple. The code is rather complicated. Is everything needed or did it came from a project that needed more coding?

Anyway, thanks a lot!!

 

best regards,

Harry

I created that as a model of my current app to play with for my project so, yea, it's got more in it than is necessary. Didn't build it for this post, just happened to already have it and didn't mark it as private. I forked and simplified it a bit for you here...

Added a few comments so you can see more what's going on. The reason I used a couple of wrappers for the video was because I wanted to both scoot the container down to make room for testing drag and resize as well as scale the size of the stage in order to more easily move things around in a smaller window - the video is 1920x1080. See...

transform: matrix(0.5, 0, 0, 0.5, 0, 0)

set on #stage-container and...

transform: translate3d(-48px, 50px, 0px);

set on #stage-wrapper

 

Also, I wanted to hide the overflow of the video. The drop-shadow for the stage is only there to help see the stage area. The font is the same one I use in the app and it's only used on the label for the checkbox.

 

I've added a few comments as well. Hope that helps.

Thanks Carvel Avis  / Swampthang,

I found the jewels. Only needed this. Works beautifully! Hard to find, extremely useful piece of excellent coding! 

best regards,

Harry

Sorry. Just something I had already done and am out of my office using my phone. Just offering it as a sample with some possible solutions even if tidbits are helpful. 

 

Hehe. You don't have to apologize. I was just wondering why as I've never used it. 

 

I know this is kind of old, but I was just reading your earlier questions about doing rotation. Here's a demo I made for another question.

This example is outstanding. Even though this is a few years old: I'd like to ask what I have to change to get the handle working in the right bottom corner. I've tried some things with little success. I don't need the rotation, so I assume it should be much simpler. Thank you.

You'll need to continue to compensate for that changed value in the other parts of the script. Unfortunately we don't have the capacity to help with logical issues like this. If you have a question specific to GSAP please let us know and we'll do our best to help! Alternatively you could look to hire someone to customize this script to your needs.
