I need to be able to resize a miniwindow without losing the hotspot callback history so that I can shrink and expand them with the mouse. Don't worry about repositioning everything inside. I just need to be able to adjust the drawing boundaries during a drag. Is it possible to accomplish currently?

I'd suggest using a separate miniwindow as the draggable spot. That way, you're dragging a miniwindow that doesn't change the whole time.

Yeesh, sounds like yak shaving. As much as I appreciate possessing the ability to work around problems, I'd rather see a clean solution instead. But thanks for the suggestion. For now I'll try it out, but I still think we need a Resize function that doesn't arbitrarily destroy all the callbacks.

You could use WindowHotspotInfo to find what the current hotspots are:

Template:function=WindowHotspotInfo WindowHotspotInfo

The documentation for the WindowHotspotInfo script function is available online. It is also in the MUSHclient help file.

Nick, I don't think I quite understand. I'll play around with this info later, but can you offer any advice on using this to recover, for example, the fact that the mouse is currently still pressed (press starts before the resize, resize destroys the callback history so the drag handler stops working) without reclicking? I mean... a way to manually set the dragging bit after re-creation might work too, but it seems like non-destructive resize functionality would be really useful in this scenario.

I see what you mean. Changing hotspots during a mouse-down isn't a great idea, because it gets confused about having a mouse-down for something that ceases to exist.

I'm not sure about the resizing. Simply allowing the box to grow or shrink wouldn't totally solve the problem, because GUI elements (like the resize graphic itself) have to move too.

Either the window would have to redraw frequently, repositioning things, or it would look silly.

My interim suggestion is to experiment with creating a new "border" window (like the old days when you resized a window in Windows, you just saw an outline of the new size). The border window could be implemented by having a transparent inside, and a grey 2-pixel or so border. This new window could be deleted and redrawn each time the mouse moves, effectively visually showing you what the new size is going to be. And then when you let go, you recreate the window with the new dimensions.

This is what I want to do. It's not that hard, and I'd be totally happy with that stuff left to the user.

I'm experimenting with Twisol's idea. I've gone and made the modifications to movewindow.lua that I ... oh hey, you've done one of them. This is why I like you so much.

<grin>

Now added a miniwindow resize function in version 4.58. Moving things inside the window around will be your problem, however the function copies the existing window contents to the top-left corner of the resized window.

Existing hotspots, images, fonts are retained.

Also added a move hotspots function so you can move the resizing hotspot.

Awesome. Technical question, though...
When I first thought about asking for this way back when, I thought the necessary code changes would be on the order of one or two lines. Actually...I didn't really look very long at the code and just sort of made assumptions about how miniwindow creation stuff worked and thought that all you would do would be to add another bool parameter to createwindow that would optionally not call deletehotspots() or whatever it's called.

I was a bit surprised to see the extent of the change. Why that way? Do I need to go and actually read through the code now to see how stuff works? :)

Abandon hope, all ye who enter here. :D

No, actually, I agree with making it its own function, at least script-side. It makes it much more obvious what exactly you're trying to do.

As far as adding a bool to Create(), there's a lot of other code in there that's irrelevant to sizing a window, which is all Resize() does. And Resize() isn't very complex; all it does, AFAICT, is copy the bitmap.

Yes I see what you mean. I suppose a flag to keep hotspots would have been simpler. Oh well, it isn't as if it was hundreds of lines of code.

Anyway, the WindowResize function keeps the existing contents (at least the original contents) which may or may not help.

I added this flag to version 4.59.
