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.
|
|
|
|
| |
Just the minimal implementation so far.

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.

Now it contains coordinates of the top-left delimiting
point and computed dimensions (instead of coorinates of
both delimiting points).
|
|
|
|
| |
This required writing a special CMake find module.
|
|

Mostly found by -Wextra.

The document maintains a list of LdDocumentObject objects.
|
|
|
|
| |
Also make the code reference properties properly.
|

So far it does not add symbols to the document,
as there is momentarily no interface for neither
the document nor the canvas.

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.
|
|
|
|
| |
The human name and area now gets resolved.
|
| |
|
|
|
|
|
| |
To accomplish this, LdSymbolArea had to be converted
to a regular boxed type.
|
|
|
|
|
| |
Also move the actual storage of symbol properties to implementations
of the abstract LdSymbol class. All the properties are read only.
|
|
|
|
|
| |
This function tries to return a symbol that corresponds
to the given identifier.

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.

There's a very strong bond between LdLua and LdLuaSymbol.
LdLuaSymbol is more like an interface to LdLua than a separate object.
|
| |
|
|
|
|
|
| |
Added GObject properties for object parameters.
Implemented methods for children management.

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.

The "new" method requires to be passed a parameter that
makes it possible to call the appropriate render function.
Stub-plemented the "draw" method.
|
|
|
|
| |
Some comments in the source code have been updated.
|
|
|
|
| |
Created LdLuaSymbol, which subclasses LdSymbol.

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.

Originally, there were three object classes defined in this file.
It would later become rather chaotic if left that way.

It now paints itself white and draws a simple grid.
Also an LdDocument can be assigned to it.

It was just too long to type and read. My mistake.
|
|
|
|
|
|
| |
Also a little change in CMakeLists.txt.
The next commit is going to change the object prefix.

Added two empty sample categories with corresponding icons.
The categories are now being loaded into the toolbar
in the main program window.
