Přemysl Eric Janouch fe996324d3 Take a better approach to drawing the grid. 
If the diagram is zoomed out too much, just use bigger steps between dots.
 2011-01-08 16:41:55 +01:00
Přemysl Eric Janouch 909a0352cc Don't draw the grid when it would be too narrow. 
This prevents eating all the memory.
 2011-01-08 12:11:08 +01:00
Přemysl Eric Janouch edd64aa132 Read terminals from Lua scripts and export them. 
Also add a missing part of LdSymbol API.
 2011-01-08 12:09:45 +01:00

Refactor a part of LdCanvas in the process.
 2011-01-07 04:52:44 +01:00
Přemysl Eric Janouch 1704b94650 Introduce structure LdCanvasRect. 
It's basically the same as cairo_rectangle_t,
just in our own namespace.
 2011-01-06 13:07:04 +01:00
Přemysl Eric Janouch 53d1de680d Change symbol clip tolerance to widget units. 
As line width is in pixels, too, this makes much more sense.
 2011-01-06 03:28:47 +01:00
Přemysl Eric Janouch 8eba321abe Redraw LdCanvas on LdDiagram changes. 2011-01-05 11:03:38 +01:00
Přemysl Eric Janouch 63f6feaa0e Add new objects to the start of LdDiagram's list. 
This way it doesn't have to go through the whole linked list
to find a place for the objects.
 2011-01-05 05:29:52 +01:00
Přemysl Eric Janouch b08217f999 Add a "selection-changed" signal to LdDiagram. 
Make existing code emit this signal.
 2011-01-05 04:37:42 +01:00

Přemysl Eric Janouch c4b8f092b7 Export cairo_{get,set}_line_width to Lua symbols. 2011-01-05 03:56:59 +01:00
Přemysl Eric Janouch 25f1186000 Draw selected objects with another color. 
Store all colors in LdCanvasPrivate and initialize them upon
object creation. This creates a base for color themes.

Make attempts to try adding an object that's not a part
of the document to the selection issue a warning.
 2011-01-05 01:11:03 +01:00
Přemysl Eric Janouch fdf1ddbbb1 Move lines around. No functional change. 2011-01-04 23:05:38 +01:00
Přemysl Eric Janouch d3e5483c84 Make adding symbols to the diagram possible. 
This required creating a simple framework for operations to LdCanvas.
It is probable that it's going to require some changes when other
operations are added. The basic idea behind it seems to be good, though.
 2011-01-04 09:54:05 +01:00
Přemysl Eric Janouch 25a0ea7ce5 Fix the "library" property in LdCanvas. 2011-01-04 04:08:05 +01:00
Přemysl Eric Janouch 820239597e Partial refactoring of LdCanvas. 
draw_symbol() had been doing too much.
 2011-01-04 00:45:44 +01:00
Přemysl Eric Janouch 2cb570f894 Split in-out parameters into separate in and out. 
In functions:

ld_canvas_widget_to_diagram_coords()
 2011-01-03 05:57:22 +01:00
Přemysl Eric Janouch 9dc1822040 Fix problems discovered while testing on Windows. 
* Set the working directory for glib-genmarshal correctly.
* Use one more path suffix when searching for glibconfig.h.
* Don't assume that gdk_screen_get_resolution() returns
  a useful value.
 2010-12-20 05:20:21 +01:00
Přemysl Eric Janouch 9178fb8d81 LdCanvas maintenance. 
* Rename ld_canvas_translate_*_coordinates() to ld_canvas_*_to_*_coords().
* Add missing parameter assertions to those functions.
* Rename local variables in draw_grid().
* Use gdk_cairo_rectangle() in expose-event handler.
* Update comments.
 2010-12-18 15:34:34 +01:00
Přemysl Eric Janouch f2f308f2f5 Make the symbol menu grab focus. 
This way when the user clicks outside the menu when it is open,
the menu will close itself first.

Keyboard input is however still not handled.

The symbol menu should be redesigned.
 2010-12-18 05:01:50 +01:00
Přemysl Eric Janouch 86e73f86c2 Rename LdDocument* to LdDiagram*. 
My bad; this name is much more appropriate.
 2010-12-16 11:34:02 +01:00
Přemysl Eric Janouch 721cc30478 Overall cleanup. 
* Add missing asserts to exported functions.
* Unify formatting.
* Fix the gtk-doc comment for ld_symbol_category_set_human_name().
* Make ld_library_load() reflect it's declaration.
* Remove an unused variable in ld_library_load_cb().
* Change all char's to gchar's.
 2010-12-16 06:51:18 +01:00
Přemysl Eric Janouch 4a946b3241 Implement diagram operations in UI.

* 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.
 2010-12-16 04:50:54 +01:00
Přemysl Eric Janouch 45aeda982b Remove redundant flags from signals. 2010-12-12 18:17:13 +01:00
Přemysl Eric Janouch a56bfd6087 LdWindowMain cleanup. 
* Restructure the initialization code.
* Move LdCanvas event mask setting to ld-canvas.c.
* Remove some redundant code.

* Update comments.

Practically no functional change.
 2010-12-12 17:56:59 +01:00
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 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 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 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 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
Přemysl Eric Janouch 354e54826f Changed the object prefix from "logdiag" to "ld". 
It was just too long to type and read. My mistake.
 2010-09-19 19:12:36 +02:00
Přemysl Eric Janouch 341f51eb41 Renamed source files. 
Also a little change in CMakeLists.txt.

The next commit is going to change the object prefix.
 2010-09-19 19:12:12 +02:00
Přemysl Eric Janouch db46ae5505 Started implementing the canvas and the document. 2010-09-17 18:53:57 +02:00
Přemysl Eric Janouch 55c25ae1bd Added basic loading of categories. 
Added two empty sample categories with corresponding icons.
The categories are now being loaded into the toolbar
in the main program window.
 2010-09-15 19:31:57 +02:00
Přemysl Eric Janouch 82cfa12920 A little bit of cleanup. 2010-09-14 07:19:00 +02:00
Přemysl Eric Janouch b230b69539 Initial commit 2010-09-13 19:24:53 +02:00
