Moving an ElementDocument programmatically

[barotto]

Hello,
I'm trying to solve an usability problem I have with my application.

I have a document that the user can move and resize.
This pose a problem when the application's client area shrinks and the document goes out of view (eg when going from fullscreen back to windowed)

So when that happens I move the document into view like so:

doc->SetOffset(Rml::Vector2f(new_x,new_y), nullptr);

So far so good, the document moves to the new position.
Unfortunately its position reverts back to the old values (and out of view again) as soon as:

1. the user tries to resize it
2. the user resizes the app's client area

What's the proper way to move a document?
Am I missing something?

SetOffset is more of an internal function, I can certainly see how that is confusing. Instead, you should set the position of the document using RCSS properties, as the document is essentially just a normal, absolutely positioned element. In particular set the top, left properties to move the window, and width, height or right, bottom to size the window.

That works, but I decided to solve the problem in a less complicated way.
Suppose I have a document with this initial style in the rml:

body {
  width: 80%;
  height: 80%;
  margin: auto;
}

So size and position are auto updated when the app's window changes. But when the user resizes and moves the document, width/height and top/left will get fixed absolute values.

When the document goes out of view, I want to reset to the initial values, as defined in the rml file.

Is there a way to do a reset? Or do I need to query the initial values when the document is loaded and then later use SetProperty()?

I tried to use ReloadStyleSheet() but it doesn't work.

Sorry, I just found the function I need: RemoveProperty().
