Michael Weghorn f504ea8b34 sd: Port LayoutToolbarMenu from ValueSet to weld::IconView
Port the toolbar popup to select the slide layout to use
from using two ValueSet widgets to using weld::IconView
instead.

This helps to be more consistent with other platform/toolkit
widgets and reduces custom widget logic.

Adjust indices used to account for the fact that
weld::IconView indices are 0-based while the ValueSet ones
are 1-based. For the particular case here, custom non-continguous
item IDs were used for the ValueSet items that
correspond to the AutoLayout enum values.
Store those custom IDs as the IDs of the weld::IconView items and
retrieve the ID again in LayoutToolbarMenu::IconViewItemActivatedHdl.

The popup can be triggered like this:

* start Impress
* in the toolbar, click on the "Slide Layout" button

LibreOffice Impress / Draw Application

The core directory for the impress/draw applications.

Think of impress as a hack on top of draw.

sd module contains impress/draw specific code, non-shared UI and part of ppt and pptx filter, few other filters too.

the slideshow UI lives here as well, the slideshow engine is in slideshow module though (including the 3D transitions engine slideshow/source/engine/opengl).

the most used filters are ODF's odp, binary ppt and OOXML's pptx. their locations are listed below:

  • odp import and export filters are in xmloff module (mostly xmloff/source/draw)

  • ppt import is in sd/source/filter/ppt (big shared chunks are also in svx)

  • ppt export is in sd/source/filter/eppt (big shared chunks are also in svx)

  • pptx import is in oox/source/ppt (and uses a lot of oox/source/drawingml and oox/source/*)

  • pptx export is in sd/source/filter/eppt (mostly in pptx-* source files) and shared part is in oox/source/export

PPTX Export / Import Filters

PPTX export filter is split into 2 parts. Impress related part is in sd/source/filter/eppt/pptx-* and the other part is in oox/source/export/ because it contains mostly code related to DrawingML, which is shared with writer and calc ooxml export.

The export filter was written in 2009 IIRC and was not much extended feature-wise lately.

Presenter Console

The main screen uses a hardware-accelerated canvas (e.g. cairo canvas), while the entire secondary screen uses a VCL-canvas that is created in sd::framework::FullScreenPane::CreateCanvas().

The secondary screen contains 3 Panes which each have 2 XWindows for the border area & the actual content, and each content Pane is backed by a sd::presenter::PresenterCanvas that wraps the FullScreenPane's canvas and does clipping.

Future Works

Add custom shapes export (see below). enhance text output, we don't write text style for indentation levels now, need to export a:lvl1pPr, a:lvl2pPr, ... elements.

PPTX import was written by Sun/Oracle and then extended in LibreOffice a lot during bug fixing. It is located in oox/source/ppt and oox/source/drawingml. The areas with most bugs (at least until today) were shape placeholders and text style inheritance.
