* Define descriptions and accelerators for actions.
* Set irrelevant actions unsensitive.
* Also remove redundant comments for clarity.
 2010-12-16 06:10:28 +01:00
Přemysl Eric Janouch 2c3345a4fd Add change notifications to properties. 
Also fix the "human-name" property in LdSymbolCategory
and correct gtk-doc comments for coordinates properties
accessors in LdDocumentObject.

Přemysl Eric Janouch fdab244e2e Rename local LdCanvas methods. 
Use a "real" prefix, as GTK+ does.
 2010-12-12 17:30:28 +01:00
Přemysl Eric Janouch f9dbe12971 Stubplement LdDocument file operations. 
Prototypes for these functions were wrong; fixed.
 2010-12-11 20:32:03 +01:00
Přemysl Eric Janouch e364267010 Add a "modified" property to LdDocument. 
The property is set to TRUE whenever the document changes.
The user may set it back to FALSE with ld_document_set_modified().

Also don't emit the "changed" signal when nothing has happened.
 2010-12-11 20:31:54 +01:00
Přemysl Eric Janouch 805089c38f Rename local LdLuaSymbol methods. 
Use a "real" prefix, as GTK+ does.

Also make the implementations of virtual functions
really static, as they prototypes were telling.
 2010-12-11 14:26:00 +01:00
Přemysl Eric Janouch afacad693d Add a main toolbar. 
So far it has no special powers. This should change in the future.
 2010-12-11 04:15:23 +01:00
Přemysl Eric Janouch fe7c270bdd Check for name collisions in symbol categories. 2010-12-11 03:49:54 +01:00
Přemysl Eric Janouch e6230576b7 Add category.json files for testing categories. 2010-12-11 03:49:53 +01:00
Přemysl Eric Janouch 67325d5f70 Read human names of categories from category.json. 
category.json contains a JSON object/table with localized
names of the category directory they are located within.

If a localized name cannot be found, the name of the category
is used as the human name, too.
 2010-12-11 03:49:46 +01:00
Přemysl Eric Janouch 74e43ceee4 Add a "human-name" property to LdSymbolCategory. 
Just as LdSymbol has a human name for localization purposes,
LdSymbolCategory also needs to have this property.

Use the human name in tooltips.
 2010-12-11 02:44:00 +01:00
Přemysl Eric Janouch aeb6e7ed58 Add a few symbols for testing. 
The lucky ones are: capacitor, resistor and diode.

More symbols can be expected later, when more cairo
functions are exported to Lua and relevant standards
become accessible to me.
 2010-12-10 23:27:45 +01:00
Přemysl Eric Janouch dea23f1204 Draw symbols from LdDocument in LdCanvas. 
Just the minimal implementation so far.
 2010-12-10 22:58:36 +01:00
Přemysl Eric Janouch 3419680f25 Implement more of LdCanvas. 
1. Add methods for coordinate translation between cairo/GtkWidget
   coordinates and LdDocument coordinates.
2. Draw the grid correctly (also make it significantly faster).
3. Place the canvas into a GtkScrolledWindow and register
   the set_scroll_adjustments signal in the GtkWidget base class.
4. Allow scrolling inside of an area of 200 x 200 units (for now).
   In the future, it should be possible to go to infinity.
 2010-12-10 22:36:41 +01:00
Přemysl Eric Janouch 37d898fb1a Change LdSymbolArea members. 
Now it contains coordinates of the top-left delimiting
point and computed dimensions (instead of coorinates of
both delimiting points).
 2010-12-10 08:57:42 +01:00
Přemysl Eric Janouch 3d3a71d5d2 Prepare the project for json-glib. 
This required writing a special CMake find module.
 2010-12-05 15:30:21 +01:00
Přemysl Eric Janouch 1d956964e2 Random fixes. 
Mostly found by -Wextra.
 2010-12-05 15:21:00 +01:00
Přemysl Eric Janouch 147cf2977a Initial LdDocument implementation. 
The document maintains a list of LdDocumentObject objects.
 2010-12-05 15:15:52 +01:00
Přemysl Eric Janouch 7a0b280854 Add a "library" property to LdCanvas. 
Also make the code reference properties properly.
 2010-11-19 07:05:44 +01:00
Přemysl Eric Janouch d31d420f59 Symbols are required to save cairo state. 2010-11-16 10:30:10 +01:00
Přemysl Eric Janouch 8f2dad4ead Added basic onscreen symbol menu. 
So far it does not add symbols to the document,
as there is momentarily no interface for neither
the document nor the canvas.
 2010-11-16 10:26:15 +01:00
Přemysl Eric Janouch 263aa9062e Formatting and naming changes in LdWindowMain. 2010-10-28 14:11:59 +02:00
Přemysl Eric Janouch 5a24eaabb2 Made Lua symbol registration more robust. 2010-10-28 09:07:47 +02:00
Přemysl Eric Janouch 9271ce1134 Separate LdLua and LdSymbolCategory. 
Originally, ld_lua_load_file_to_category() was adding
registered symbols into a passed LdSymbolCategory object.
This interface has been rewritten to be more generic
by using callbacks to notify about new symbols.
 2010-10-27 20:49:21 +02:00
Přemysl Eric Janouch 8b5fa9a49a Implement parts of Lua symbol registration. 
The human name and area now gets resolved.
 2010-10-27 20:05:52 +02:00
Přemysl Eric Janouch 1c5127068e Fix gtk-doc comments. 2010-10-27 18:18:37 +02:00
Přemysl Eric Janouch 121d923d29 Added an "area" property to LdSymbol. 
To accomplish this, LdSymbolArea had to be converted
to a regular boxed type.
 2010-10-27 18:15:31 +02:00
Přemysl Eric Janouch 9156953cc9 Add more properties to LdSymbol. 
Also move the actual storage of symbol properties to implementations
of the abstract LdSymbol class. All the properties are read only.
 2010-10-27 16:52:00 +02:00
Přemysl Eric Janouch aa33db342b Added ld_library_find_symbol(). 
This function tries to return a symbol that corresponds
to the given identifier.
 2010-10-26 20:01:52 +02:00
Přemysl Eric Janouch 979308aa7f Manage LdLibrary children in a GSList. 
The previous method of containment, that is using GHashTable,
did not list children in any particular order.

Also names of children were duplicated. One copy has been
stored as a hash table index and another was present in the
child itself.
 2010-10-26 16:41:03 +02:00
Přemysl Eric Janouch 9a242786b1 Redesign and implement the basic parts of LdLua. 
There's a very strong bond between LdLua and LdLuaSymbol.
LdLuaSymbol is more like an interface to LdLua than a separate object.
 2010-10-26 16:40:53 +02:00
Přemysl Eric Janouch 2b9b543402 Implement the LdSymbol "name" property. 2010-10-26 16:40:21 +02:00
Přemysl Eric Janouch ba3b348dfd Implement the rest of LdSymbolCategory. 
Added GObject properties for object parameters.
Implemented methods for children management.
 2010-10-26 16:40:08 +02:00
Přemysl Eric Janouch ffc57249c8 Make LdLibrary call LdLua to load symbol scripts. 2010-10-26 13:58:39 +02:00
Přemysl Eric Janouch e0e63649dc Redesign the library and related components. 
This step is needed, since the current design is quite chaotic
and it would not be possible to finish the application.

There's still a lot to be done.

After this step, it's time to implement the rest of LdLua.
 2010-10-26 13:58:33 +02:00
Přemysl Eric Janouch 0c9b297e50 Implement part of LdLuaSymbol. 
The "new" method requires to be passed a parameter that
makes it possible to call the appropriate render function.

Stub-plemented the "draw" method.
 2010-10-17 14:05:53 +02:00
Přemysl Eric Janouch 9fc354e066 Implement a few bits of LdLua. 
Some comments in the source code have been updated.
 2010-10-17 14:05:53 +02:00
Přemysl Eric Janouch efe45e9601 Convert LdSymbol into an abstract class. 
Created LdLuaSymbol, which subclasses LdSymbol.
 2010-10-17 14:05:53 +02:00
Přemysl Eric Janouch 23a1f25130 Created LdLua class. 2010-10-17 14:05:53 +02:00
Přemysl Eric Janouch c0ec389b59 Renamed LdSymbolLibrary to LdLibrary. 2010-10-17 14:05:53 +02:00
Přemysl Eric Janouch 5da5689541 WIP: Refactoring of the library and symbols 2010-10-17 14:05:53 +02:00
Přemysl Eric Janouch 25668c2073 Updated to new GTK+. 
FindGTK2.cmake required a change for successful program compilation.
It seems that gdk_pixbuf has been put as a separate library.

The new tools also generate a slightly different version
of marshallers, so I've added it to the tree.
 2010-10-17 13:36:03 +02:00
Přemysl Eric Janouch f250621519 Split ld-symbol-library.c. 
Originally, there were three object classes defined in this file.
It would later become rather chaotic if left that way.
 2010-09-20 18:18:30 +02:00
Přemysl Eric Janouch f675a7c07c Require Lua 5.1 and GTK+ 2.12. 2010-09-20 17:28:23 +02:00
Přemysl Eric Janouch efc3ad6f5c Implemented a skeleton of LdCanvas. 
It now paints itself white and draws a simple grid.
Also an LdDocument can be assigned to it.
 2010-09-20 05:29:41 +02:00
Přemysl Eric Janouch 2dd5dbaf67 Automatized generation of marshallers. 2010-09-19 19:12:36 +02:00
Přemysl Eric Janouch b66704114e Little improvements, overall cleanup. 2010-09-19 19:12:36 +02:00
Přemysl Eric Janouch 65bbe06267 Add marshaller files generated by glib-genmarshal. 2010-09-19 19:12:36 +02:00
