There are a number of mark views, but we're only interested in the one that belongs to the editing window. Ignore the virtual device of the slide sorter and everything else. With this, a shape remains selected after resized, and can be resized multiple times again properly. Change-Id: I7f31c72567b9d01aaa75871ff5d1efdb3151a0e4
A quick overview of the LibreOffice code structure.
Overview
You can develop for LibreOffice in one of two ways, one recommended and one much less so. First the somewhat less recommended way: it is possible to use the SDK, for which you can read the API docs here. This re-uses the (extremely generic) APIs we provide for macro scripting in StarBasic.
The best way to add a generally useful feature to LibreOffice is to work on the code base however. Overall this way makes it easier to compile and build your code, it avoids any arbitrary limitations of our scripting APIs, and in general is far more simple and intuitive - if you are a reasonably able C++ programmer.
The important bits of code
Each module should have a README file inside it which has some
degree of documentation for that module; patches are most welcome to
improve those. We have those turned into a web page here:
However, there are two hundred modules, many of them of only peripheral interest for a specialist audience. So - where is the good stuff, the code that is most useful. Here is a quick overview of the most important ones:
| Module | Description |
|---|---|
| sal/ | this provides a simple System Abstraction Layer |
| tools/ | this provides basic internal types: 'Rectangle', 'Color' etc. |
| vcl/ | this is the widget toolkit library and one rendering abstraction |
| svx/ | graphics related helper code, including much of 'draw' / 'impress' |
| sfx2/ | core framework: document model / load/save / signals for actions etc. |
| framework | UNO wrappers around the core framework, responsible for building toolbars, menus, status bars, and the chrome around the document using widgets from VCL, and XML descriptions from */uiconfig/ files |
Then applications
| Module | Description |
|---|---|
| desktop/ | this is where the 'main' for the application lives, init / bootstrap. the name dates back to an ancient StarOffice that also drew a desktop |
| sw/ | writer. |
| sc/ | calc |
| sd/ | draw / impress |
There are several other libraries that are helpful from a graphical perspective:
| Module | Description |
|---|---|
| basebmp/ | enables a VCL compatible rendering API to render to bitmaps, as used for LibreOffice Online, Android, iOS, etc. |
| basegfx/ | algorithms and data-types for graphics as used in the canvas |
| canvas/ | new (UNO) canvas rendering model with various backends |
| cppcanvas/ | C++ helper classes for using the UNO canvas |
| drawinglayer/ | code to render and manage document drawing shapes and break them down into primitives we can render more easily. |
Finding out more
Beyond this, you can read the README files, send us patches, ask
on the mailing list libreoffice@lists.freedesktop.org (no subscription
required) or poke people on IRC #libreoffice-dev on irc.freenode.net -
we're a friendly and generally helpful mob. We know the code can be
hard to get into at first, and so there are no silly questions.
