All add() functions from wxSizer returns a point of wxSizerItem, which points to the new wxSizerItem they just created. In your case, this is your spacer. So as long as you keep tracks of these returned wxSizerItem pointers, you can modify them

I don't know, but EVT_LIST_ITEM_DESELECTED definitely didn't work with my virtual lists.

why not try to put all 3 wxListView inside a boxsizer

Hello all,

I know this is a known issue and it's raised 14 years ago. However, do we have a solution for this after 14 years?

Thank you

BTW, wxListCtrl in the virtual mode has RefreshItems() , in case you would need to refresh only a subset of items. BTW2, I hope it was understood but just to be sure: you also need to tell the list how many items are there with SetItemCount() . BTW3, the methods relevant for the virtual mode are li...

Thank you so much!`

"The application provides items text on demand" about wxLC_VIRTUAL. I'm not too sure about what it means. https://forums.wxwidgets.org/viewtopic.php?p=172585#p172585 This mentions a database as data source, but the principle is the same. So if I understand correctly, by making the listCtr...

If your list happens to be displayed only in the report, what about using wxLC_VIRTUAL? Otherwise, there is probably not much to do. Its lack of elegance aside, Is there an actual issue (performance etc.) with the current implementation? Hi, I'm using wxLC_REPORT style. I just read the documentatio...

I have a std::set to hold some data that I want to display in a ListCtrl, and this std::set is constantly being modified so every time it gets modified, I need to sort it and refresh the ListCtrl. The current way I have is something like this ListCtrl * myList; void refreshList(const std::set& m...

My code just somehow magically worked!!! I didn't change anything. Thx for all the advice guys!

As doublemax said, you probably did something wrong in myClass ctor. This works as expected #include <wx/wx.h> class myClass : public wxTimer { public: myClass() {}; void Notify() override { wxLogMessage("myClass::Notify"); } }; class MyFrame : public wxFrame { public: MyFrame() : wxFrame...

doublemax wrote:That looks ok. Did you call the default wxTimer constructor?

Yes, I'm not overriding the constructor. My constructor looks something like this

Hello all, I'm trying to create a simple class that derives from wxTImer. So I have code like this: myClass.h class myClass : public wxTimer { public: myClass(); virtual ~myClass(); void Notify() override; } myClass.cpp /// ctor and dtor void myClass::Notify() { wxLogMessage("Notified"); }...

Wow it actually worked! I knew the code could actually launch async threads but had no idea why they were still "synchronous" when I used std::launch::async. Thank you! void MyClass::OnButton_1Click(wxCommandEvent& event) { auto fut = std::async(std::launch::async, [this]{ /// code}); ...

I'm afraid that I can't post the complete source code since what I'm working on doesn't mean to be an open source project. I'm sorry. I can only write some simple code to demonstrate what I'm trying to do here. And I don't quite understand your questions. I'm not using any pointers in std::async, ex...
