Re: How to prorer set wxGridCellRenderer for xGrid by SetColAttr()?
Thank you for right direction! I've tried: wxGridCellAttr* pAttr = new wxGridCellAttr; pAttr->IncRef(); pAttr->IncRef(); Problem still exists. After your answer, I've started look for IncRef() and SetCellEditor and have found very good explanation (don't know is it good to put it here?): From vadim ...

How to prorer set wxGridCellRenderer for xGrid by SetColAttr()?
Hi, I will need to create own wxGridCellRenderers and wxGridCellEditors in my proj. So, I try to understand how it should work. First, I've found that I need to use IncRef() before SetColAttr(). Now,I have another error when I close an app: "Assert GetEventHandler()==this failed in ~wxWindowBas...

Re: How should I store wxStrings in memory?
Thanks!doublemax wrote:Make your life easy
But I want a faster life too
I'm not sure, that vector, list, etc. will be faster than wxString * array[].
I want a direct access if the array will not grow.
Am I wrong?
Should I forget about direct access?

Re: What is a correct way to fill wxGrid from wxSQLite3Table?
You need to create your GridTable Class Thanks! Will try to do it. Now, I just can fill wxGrid from a table like this. try { wxSQLite3Statement ls=db->PrepareStatement("SELECT id,name FROM table ORDER BY id"); wxSQLite3ResultSet lr=ls.ExecuteQuery(); int ln=lr.GetColumnCount(); grid_table...

What is a correct way to fill wxGrid from wxSQLite3Table?
I don't want double buffering.
First, I've got wxSQLite3Table as a result of execution of my SQL query.
Second, I need to copy all data from wxSQLite3Table to wxGrid.
Third, I need to destroy wxSQLite3Table.
Is it a correct way?
Thanks!

Re: What to do if I need a small database
you can add the wxSQLite3 and the SQLite Amalgamation source files to your project as if it were your own source files. Yes! It works. Just add to project folder: sqlite3.c sqlite3.h wx/wxsqlite3.h wx/wxsqlite3.cpp wx/wxsqlite3def.h wx/wxsqlite3opt.h And add project path to search compile path. dou...

No, you can add the wxSQLite3 and the SQLite Amalgamation source files to your project as if it were your own source files. Good. Will try to do it. But I'm afraid it will need more skills that I have. You can derive your own class from wxGridTableBase and set it with wxGrid::SetTable(). Yes. Thank...

Re: What to do if I need a small database
For around 1000 lines reading and writing to a text file should be fast enough. Thank you. Alternatively you could use sqlite + wxSQlite3 which works with local files and can be embedded into your application. In this case, I will need to install SQLite3. But I really want all-in-one. And the probl...
