"\n" doesn't not work on windows ? Topic is solved

[Maeglix]

Hey !

I am building a wxTreeCtrl and i would like that some of the item to be on multiple line.
So i use "\n" in the wxString i want to be on multiple line.

It works perfectly on linux but on windows it just ignore the "\n". For example "test\ntest" becomes "testtest".

So did i do something wrong or is this normal ? Is there any workaround ?

Thanks for your help.

Perhaps the native undlerlying control on MSW (tree view) does not support multiline text of its nodes?

I don't know. In this case i would like to know if there is an other way to do what i want.

You can try to use "\r\n"
"\n" should be valid on the command line

I tried, it didn't work.

Altough i couldn't find any "official" confirmation on MSDN, i'm pretty sure this is the case. I can't remember to have ever seen a multi-line text in a standard tree control under Windows.

Ok thank you so i will try to find another way.

Maybe the generic tree control would work. I don't remember how to use it on windows though.

wxGenericTreeCtrl does not properly support multiline node labels either (they overlap).

Code: Select all

#include <wx/wx.h>
#include <wx/treectrl.h>
#include <wx/generic/treectlg.h>

class MyFrame : public wxFrame
{
public:
    MyFrame() : wxFrame(NULL, wxID_ANY, _("Test"))
    {
        wxGenericTreeCtrl* ctrl = new wxGenericTreeCtrl(this, wxID_ANY);
        ctrl->AddRoot("Root\r\nLine2");
        ctrl->AppendItem(ctrl->GetRootItem(), "Item 1\r\nLine2");
        ctrl->AppendItem(ctrl->GetRootItem(), "Item 2\r\nLine2");
        ctrl->ExpandAll();
    }	
};

class MyApp : public wxApp
{
public:	
    bool OnInit()
    {
        (new MyFrame())->Show();
        return true;
    }
}; wxIMPLEMENT_APP(MyApp);

wxDataViewTreeCtrl does not seem to support the feature too but I never used the class so I may have not used it properly

Code: Select all

#include <wx/wx.h>
#include <wx/dataview.h>

class MyFrame : public wxFrame
{
public:
    MyFrame() : wxFrame(NULL, wxID_ANY, _("Test"), wxDefaultPosition, wxSize(200,200))
    {
        wxDataViewTreeCtrl* treeCtrl = new wxDataViewTreeCtrl(this, wxID_ANY);
        wxDataViewItem rootItem = treeCtrl->AppendItem(wxDataViewItem(0), "Root\nLine2");        
    }
};

class MyApp : public wxApp
{
public:	
    bool OnInit()
    {
        (new MyFrame())->Show();
        return true;
    }
}; wxIMPLEMENT_APP(MyApp);
