wxPropertyGrid -> Append Crash Topic is solved

[heyufool1]

Hi! I have a property grid window made and put into an AUI manager. Now when I select an object on my screen (it's a level editor) I want the property grid to fill up with the selected object's properties. However when I try to do this using:

Code: Select all

g_ObjectProperties->Append(new wxIntProperty("X", "X Position", 0));

I get an "Unhandled exception at 0x00000000" error and it points to this method, at the closing bracket:

Code: Select all

wxPGProperty* wxPropertyGridPageState::DoAppend( wxPGProperty* property )
{
    wxPropertyCategory* cur_cat = m_currentCategory;
    if ( property->IsCategory() )
        cur_cat = NULL;

    return DoInsert( cur_cat, -1, property );
}

I tried using the Append method to add properties in the constructor of the object properties window and it works but not when I try to append it later on. Anyone else have as similar problem?

Can you show more context?

Make sure the g_ObjectProperties pointer is OK, a garbage pointer would be the most common cause for that kind of problems

Ah-HA! The problem was that I had an array declared with 3 indexes where in reality I wanted and used 4.

Code: Select all

OgreView* g_Views[3];

vs.

Code: Select all

OgreView* g_Views[4];

I thought that would give a fatal error or something if I tried to put data in a nonexistent index so I never caught it, but I found it now, changed it, and it works. All of this just because the array of windows unrelated to the ObjectProperties window was too small... Gotta love programming Thanks for your help!
