Re: Serial posters who waste our time

I would also like to thank doublemax for his untiring patience and support on these forums.

Why anyone would seek to criticise someone who is trying to help them is beyond me.

Re: is there Outlook style Vertical menu Control with wxWidgets?

It's an old code and seems to be throw away by author.

Re: is there Outlook style Vertical menu Control with wxWidgets?

Do you mean an accordion control like the one here?

(Please scroll down on that link, there are some pictures in the Readme.md).

Re: Remove selection ring from the grid

I think that I have done this before using wxGrid::SetCellHighlightPenWidth with a value of zero.

It is worth noting the difference between cell selection and cell highlight in this case.

Re: wxFreeChart - Request for Opinions

Well stripping out the "Fire" code and "Observable" was rather easier than I was expecting. Also implementing some simple events is not to bad. What is harder is deciding a good way to propagate them. My current thoughts are that every object which can change is derived from wxEvtHandler and posts a...

Re: wxFreeChart - Request for Opinions

Nice chart! Also a "nice labels" kind of thing should be there as an option. I have implemented a 'nice' label numbering (as per the algorithm in this discussion http://stackoverflow.com/questions/8506881/nice-label-algorithm-for-charts-with-minimum-ticks), but not sure if this is what you mean. P.S...

Re: wxFreeChart - Request for Opinions

I have created a branch in Github https://github.com/iwbnwif/wxFreeChart/tree/remove_fire for getting rid of the Fire mechanism. The aim is to restore the functionality of the demos only using wxEvent. AFAIK that is only: Dynamic data Scrolling windows That is exactly what i did when i added "intera...

Re: wxFreeChart - Request for Opinions

I am joining in as i would really like to participate in adding features and modernizing it. That's great, thanks! The "FIRE" events do really bother me and honestly i dont understand how they work or why they are there since wxWidgets offers a better event mechanism that we could implement there. ...

Re: Executables with wxFreeChart running in 64 bits mode

Hi, I found the same problem with wxWidgets 3.1.

I uploaded a new version of the makefile.gcc here:

wxFreeChart - Request for Opinions

I am working on some updates to a cloned version of wxFreeChart (the original is on wxCode). This isn’t going to be a too major overhaul as I will be ‘time boxing’ :), but I hope to fix some bugs and make some significant improvements. My main aims are: Improve the Doxygen documentation 'Modernise’ ...

Re: Storing a wxVector of derived classes

Okay, so I think I found the magic incantation needed to get this to work 8) If I have a base and derived class like this: class Foo { public: Foo(int a) { A = a; std::cout << "Foo ctor: A=" << A << std::endl; } // Very important for dtor to be virtual. Google "When is a virtual destructor needed?"!...

Re: Storing a wxVector of derived classes

I understand that it would probably be best to use the STL and would do in my own application. But for this time I would prefer to keep the same requirements as the main wxWidgets framework if possible. But if you still want to keep the same requirements as wxW you can use std::vector with wxXXXPtr....

There is some documentation here, although it is for a derived class.

Re: Storing a wxVector of derived classes

Thank you PB and Catalin for the replies.

My main reason for avoiding STL in this case is so not to have a dependency on C++11 to build the library.

Storing a wxVector of derived classes

I am working on some updates to the wxFreeChart library. The library includes datasets and data series. A dataset is basically a container for related data series, where a data series is essentially a sequence of data points to be graphed. I would like to refactor the dataset implementation to use a...
