wxDataViewListCtrl on click item action not executing.

[doublemax]

I'm pretty much out of ideas, but i still think it's something simple

Does the "dataview" sample work for you?

It shouldn't make any difference, but can you try with a static event table instead of the Bind() call?

If you can use a debugger, try tracing into the Bind() call and check if something unexpected shows up.
You could also set a breakpoint at "wxdataview_selection_changed_callback" in /src/gtk/dataview.cpp and check if the code reaches that point.

I just checked the dataview sample, for some reason out of the 4 tabs, only the first tab, that is MyMusicTreeModel is firing events in the bottom section, in the wxDataViewListCtrl tab I'm not even able to toggle the check box. This is strange, If I remember correctly this sample worked before, can't guarantee but, could be wrong.

I tried nothing shows up, I'm out of ideas too at this point, I'm going to try to build and run this on a different machine, maybe something is broken in this machine.

EDIT: Just checked on a different machine does not work. I think its a bug then.

Hi,
What OS and GTK version do you use?
Did you build the library yourself or installed it from the repo?

Thank you.

I am using Arch Linux, I am not really sure, how to know the GTK version, but I have download wxWidgets from the official repositories, package name was wxgtk3 which is on version 3.0.5, but if I run `pacman -Qi gtk3` I get

Hi,
what you do is run the sample and then "Ctrl+Alt+Middle click".

This will give tou the info.

Thank you.

Ah! Nice, I didn't knew about this, does all wx applications have this feature?

Here is the info by the way,

[doublemax]

I usually don't work under Linux, but i have one VM for occasional testing.

The dataview sample doesn't have log output for item selections on the third page (wxDataViewListCtrl) by default. But i confirmed that they do get generated with a small patch to the sample.

(Around line 930)

Code: Select all

lc->Bind(wxEVT_DATAVIEW_ITEM_VALUE_CHANGED, &MyFrame::OnListValueChanged, this);
// new line below
lc->Bind(wxEVT_DATAVIEW_SELECTION_CHANGED, [this, lc](wxDataViewEvent &e) { 
    wxLogDebug("dataviewevent row %d", lc->ItemToRow(e.GetItem()));
});

But that was with a relatively new wxWidgets version from GIT. Can you test with that or at least with version 3.1.4?

I just fired up a Ubuntu VM, cloned my repository, and tried the same thing, its not working in Ubuntu as well :/

Here is the GTK info,


EDIT: I tested with wx 3.1.4, with the added code you sent, it prints to the console fine.

I guess this means it was/is a bug in 3.0.5. I can't find any ticket on the bug tracker about this, but then again, its search function is horrible...

You could try, but i doubt the 3.0.x path will be fixed. Can't you use a 3.1.x version?

Is it stable for use? Also I was using what was available in the default repositories, which is 3.0.x. Should I compile and install 3.1.x myself then?

Hi,
You don't have to install it.
You can just download it, build it it, and then use its wx-config for building you software. And also build and run the sample.

To build:

1. Download and unpack in for example ~/wxWidgets-3.1.4
2. cd ~/wxWidgets-3.1.4
3. mkdir buildGTK
4. cd buildGTK
5. ../configure --enable-debug --with-gtk=3 && make

Then use ~/wxWidgets-3.1.4/buildGTK/wx-config --cxxflags and ~/wxWidgets-3.1.4/buildGTK/wx-config --libs for building your software.

Thank you.

And you are certainly encouraged to use latest release version. It may not be marked as stable by *nix distributions, but it eventually will when it becomes 3.2.0 (hopefully in the next couple of month).

I tried building it with wx version 3.1.4, it is still not working, nothing prints to the console no error, I think there is something wrong in my code. I have to review the whole project I suppose.

Hi,
Yes, something is very fishy happenning there.

Try to create the control with "this" (Browser) pointer as a parent.

If that doesn't help - strip down you code until it starts working.

And do use the:

Code: Select all

wxDVC->Bind()

code and without the ID of the control.

Thank you.
