2011-07-08A lightweight version of lua::state::pushclosure which handles the simple casesPavel Labath2-3/+12
2011-07-07FbTk::Lua - a class which augments lua::state with additional featuresPavel Labath3-0/+183
2011-07-02Luamm: add lua_istable C++ wrapperPavel Labath1-0/+1
2011-07-02Add a version of lua::state::loadstring which accepts std::stringPavel Labath1-0/+1
2011-07-02Store menus if smart pointers (RefCount)Pavel Labath7-31/+15
This was originally intended to be a bugfix for an memory error reported by valgrind (accessing freed memory). While debugging it, I found the menu ownership semantics confusing (setInternalMenu() et al.), so I decided to get rid of it and store it in smart pointers everywhere. Looking back, I'm not sure if this was worth all the trouble, but the good news is that the valgrind error disappeared. :)
2011-07-02Add a reset() function to FbTk::RefCountPavel Labath1-0/+1
to make it's interface more compatible with other smart pointers.
2011-06-27A veeeery rough implementation of lua menu parsersPavel Labath3-4/+4
2011-06-26Mark FbTk::StringConvertor as NotCopyablePavel Labath1-1/+3
2011-06-19Fix saving of resources.Pavel Labath1-29/+66
2011-06-16Vector resources can now specify which char to use as delimitersPavel Labath1-2/+2
when saving/loading to/from string representation. This is needed for the next commit.
2011-06-16Add LocaleStringTraits resource classPavel Labath1-2/+19
for resources which need to work with localised strings.
2011-06-16Replace ResourceManager with the lua versionPavel Labath1-0/+8
Loading of an init file with the new manager works ok. Saving and restarting is still not completed. This touches many files because i removed the alternative name of resources. Unlike Xrm, lua does not have native support for alt names. It should be fairly easy to add them, but I think that is unnecessary and would be confusing.

2011-06-15Make lua resource manager automatically initialize lua state if neededPavel Labath1-0/+5
2011-06-15Add a function for converting from XResources to lua onesPavel Labath3-0/+21
2011-06-15Lua resources: Add support for saving of boolean valuesPavel Labath1-6/+15
2011-06-15Factor out "session." from resource namesPavel Labath4-13/+19
this reduces typing and it makes more sense in lua, since there the resources are implemented as hierarchical tables and the topmost table has to be handled a bit specially.
2011-06-15Move more common stuff of (L)ResourceManagers to their base classPavel Labath4-80/+41
2011-06-15Avoid a "converting to int from foo" compiler warningPavel Labath1-1/+1
2011-06-15Add support for array lua resourcesPavel Labath2-33/+48
2011-06-15Simplify FbTk::Resource template classPavel Labath2-24/+244
by outsourcing the conversion from string/lua to the specific type (and back) to a separate class. This change touches a lot of files because the interface of FbTk::Resource changed slightly. However, the changes are minor.
2011-06-15A rough version of resource implementation in luaPavel Labath6-35/+443
I added a new class, LResourceManager, which should handle loading and saving of resources like the old ResourceManager, only it does that with the help of lua. I moved the common features of the two managers (interface + a few functions) to a common base class ResourceManager_base. I augmented the Resource_base class with two new functions (setFromLua and pushToLua) which are used by the lua RM instead of getString and setFromString. Parts of the new RM are written in lua. To avoid loading scripts from a file at runtime I decided to link compiled lua code straight into the executable. For this purpose I created a small script which converts a binary file into a declaration of a C array of bytes.

2011-06-15Remove the possibility to transport exceptions through lua codePavel Labath2-54/+9
It's impossible to do this without C++0x features (we need std::exception_ptr).
2011-06-15c++ lua binding: get rid of variadic templatesPavel Labath1-5/+44
See how variadic templates are good. They enabled me to write those four functions as one.
2011-06-15c++ lua binding: get rid of shared_ptrPavel Labath2-102/+108
It was pretty underused anyway. I was just lazy to write a proper destructor.
2011-06-15c++ lua binding: get rid of deleted functions and rvalue referencesPavel Labath2-48/+25
2011-06-15c++ lua binding: replace std::function with FbTk::SlotPavel Labath2-24/+36
std::function is superior, but not supported on old compilers
2011-06-15Prepare the Slot classes to be used as lua callbacksPavel Labath2-64/+117
Added some polish around them and, to mark this special occasion, moved them out of the SigImpl namespace. PS: This partially reverts commit 0775350fee345e37fb59835dda4d85664346b606, since I had to reintroduce ReturnType template parameter, because it will be used in lua. But Signal classes remain without the ReturnType, because I still cannot imagine how would it be used.
2011-06-15C++ binding for luaPavel Labath3-0/+810
copied from conky (http://conky.sf.net) and relicensed. Since I am the person who wrote it in the first place there should not be a problem with licence conversion.
2011-06-15Integrate the lua build system into oursPavel Labath1-0/+1
2011-06-15Add template copy constructor to FbTk::RefcountPavel Labath1-2/+8
and remove a an "almost" copy constructor (almost, because it takes a non-const reference parameter) which was useless.
2011-05-10Make SignalTracker always disconnect itself from SignalsPavel Labath1-4/+3
previously, the tracker disconnected itself only when the caller passed withTracker = true to the leave() function. However, the default value was for the parameter was false. Non disconnecting from signal when stopping tracking creates very dangerous situation because the signal still holds a pointer to the tracker. This resulted in a segfault when exiting fluxbox, because the tracker (FluxboxWindow) got destroyed before the signal (BScreen::focusedWindowSig), and the signal was using an invalid pointer when it tried to disconnect itself from the tracker. Instead of setting withTracker to true by default or changing all invocations of leave(), I decided to make the tracker disconnect itself unconditionally because I could not find a use case for the opposite behaviour. PS: This message is in fact longer than the actual commit.
2011-05-10Remove all trace of Observers and SubjectsPavel Labath7-344/+1
this marks the completion of the transition to FbTk::Signal
2011-05-10Added FbTk::MemFunBind - a functor which binds all arguments of a functionPavel Labath1-0/+94
2011-05-10Make FbTk::MemFun[12] inherit from std::unary/binary_functionPavel Labath1-2/+3
this way, they can be used as inputs to std::bind1st and friends
2011-05-10Make FbTk::MemFun[0-3] use their ResultType parameterPavel Labath1-33/+33
previously they declared the parameter, but ignored the return value of the member function. I've changed it so they pass the return value, if it is not void. MemFunSelectArg didn't have the ReturnType template parameter, so I added it for consistency. Since I was already editing the, I made all the operator()s const.
2011-05-10Last round of simplification of Signal/Slot classesPavel Labath4-108/+72
- merged all the common stuff from 0,1,2,3 argument versions into one common base class - removed ReturnType template parameter as it was instantiated with "void" everywhere and the current ignores the return value of the callbacks anyway
2011-05-10Don't crash when a slot is deregistered in the middle of signal processingPavel Labath1-15/+46
this was possible (and used) with FbTk::Subject, but the implemetation of FbTk::Signal didn't support it, which made it impossible to continue with conversion.
2011-05-10Simplify Slot.hhPavel Labath2-254/+70
Replace CallbackHolder, FunctorHolder and SlotHolder with a (smaller) set of polymorphic classes. SignalHolder now stores a (smart) pointer to the class.
2011-05-10Make RefCount<> more sensiblePavel Labath6-12/+16
the previous version of operator*() made no sense. E.g., it violated the invariant (*ptr).foo <=> ptr->foo. The dereferencing operator now returns a reference to the pointed-to object, rather than a pointer to it. I also added a bool conversion operator, which can be used in testing the NULL-ness of the pointer. Anyone wondering if that could be done in a simpler way is encouraged to read <http://www.artima.com/cppsource/safebool.html>. And, finally, I removed the mutable flag from the m_data member, since it does not need it.
2011-05-10Remove the Observer dependency from FbTk::MenuPavel Labath2-7/+3
2011-05-10Convert FbTk::Theme::reconfigSig and friends to the new Signal systemPavel Labath5-12/+11
I removed the const versions of reconfigSig() in the process since FbTk::Signal has no const methods anyway.
2011-05-10Simplify FbTk::Signal template classes a bitPavel Labath1-64/+30
basically, i just got rid of Signal[0-3] classes and moved their contents to the appropriate specialization of FbTk::Signal also, this fixes the no matching function for call to 'MemFunIgnoreArgs(FbTk::Signal<void, FbTk::SigImpl::EmptyArg, FbTk::SigImpl::EmptyArg, FbTk::SigImpl::EmptyArg>&, void (FbTk::SigImpl::Signal0<void>::*)())' error i had in the following commit.
2011-05-08Can check CARDINAL properties in CLIENT PATTERNSnacitar sevaht2-19/+38
Introduces a new member function, FbWindow::cardinalProperty() This change also changes other code that previously used FbWindow::property() to do the same thing as the new function; this reduces code duplication. There are still some bits of code (Ewmh.cc, extractNetWmIcon()) that use FbWindow::property() to retrieve XA_CARDINAL values, but as the new method is designed for getting a _single_ property, and that code uses FbWindow::property() to retrieve the number of values present, and then grab all of them; it's a different use case. I opted to not try to make cardinalProperty() into some monolithic all-purpose cardinal method; FbWindow::property() works just fine for that. This change also adds an optional (default=NULL) boolean to FbWindow::textProperty and friends that allows the caller to determine whether or not a value was actually retrieved. This was necessary for integrating FbWindow::cardinalProperty with the codebase, and it seemed to fit with FbWindow::textProperty as well. Prior to this change, if you got a return value of "", you wouldn't know if you successfully retrieved the value which happened to be blank, or if you failed to retrieve the value. Now, you can pass the address of a boolean if you so choose in order to differentiate these situations; the same applies to the new FbWindow::cardinalProperty().
