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...

Re: Auto-Update System
Hi, Whichway did you go? Any challenges met? Unfortunately I had to take a sabbatical from software development so never got chance to use these in anger. From memory, webupdate had some compile problems, but I got it to roughly work in the end. On the otherhand, winsparkle 'just worked'. Also, it i...

There are also some concise instructions here that seem to always work for me on Windows 10.

Re: Freechart 1.6
First there is no easy way to change the data in a dataset, at least that I have found. And the instance variable for the data is private to the class. I am not sure about exactly how the license work, but this makes it difficult to just replace the data in the dataset. If the instance variable was...

Re: Freechart 1.6
Hi, I got a chart to draw by including the src and include directories into my project. This is not for production use, it is just a tool so although it is cumbersome, it works. Glad you got it to work. I haven't played with the build files at all, but instead have a separate project setup in Codeli...

GNU Radio - OpenGL Charting
I still think that wxFreeChart is the way forward for wxWidgets charting and feel sorry that I haven't had time to work on it at all :oops: I have been working on other (non-software) projects and stumbled across GNU Radio https://github.com/gnuradio/gnuradio. Interestingly it offers both Qt and wxW...

Re: wxEVT_SHOW not fired on Top Level Window creation
Sorry for the delay. I have just checked under Ubuntu 14.04 LTS and the behaviour is the same as on MSW.Just in case - check that it is the same on all 3 major platforms.
Unfortunately I can't check on OSX.

Re: wxEVT_SHOW not fired on Top Level Window creation
Ah, got to the bottom of this.
wxEVT_SHOW is fired before wxEVT_ACTIVATE, I didn't realise that

wxEVT_SHOW not fired on Top Level Window creation
Should a wxEVT_SHOW be fired when a new top level window (main frame) is created?
I appear to be seeing random behaviour where it is sometimes fired and sometimes not on successive start-ups of my app.

Re: Smth wrong with wxMessageDialog?
This is a little strange because I use wxMessageBox in almost exactly the same way as your first example on Ubuntu 14.04 and it works fine! For example, the following: int response = wxMessageBox(msg, "Confirm", selection.size() > 1 ? (wxYES_NO | wxCANCEL) : wxYES_NO); if (response == wxYES) { .... ...

Re: wxGrid: how to format float dropping trailing zeros
You'd have to remove the zeros after the string is created. But as this happens deep inside wxGrid, it'll be hard to change that. I think that it should be possible with a custom wxGridCellRenderer . The best place to start looking would be in `wxGridCellNumberRenderer::GetString` or `wxGridCellFlo...

Hi, a) Can I use wxAutomationObject with OOO ? If yes, has anybody an example with Writer ? It may be possible, but (obviously) only on MSW. It is worth having a look at the examples here: https://www.openoffice.org/udk/common/man/spec/ole_bridge.html But sorry, I never tried this. b) Is there also ...

Re: the problem of "wxReportDocument" for print preview
Hello, No problem, this is a sort of sideline for me too! Although wxReportDocument has a lot of promise, in the end I found LimeReport and wrote some wxWidgets bindings for it. Of course it would be nice to have a native wxWidgets reporting framework, but this is a good solution for me at the moment.

Re: what wxDC shoud i use ?
can we treat the each drawn object on wxPaintDC as a window object so we can track their position, width n height and even has a onklick function on it'own class ? No, a wxDC has no real 'memory' of what has been drawn on it, other than the colour of the pixels that have been set. If you want to tr...
