Some controls have a dedicated method for this, e.g. ChangeValue() vs SetValue() in wxTextCtrl. But wxSlider does not, so you have to implement a solution in your code. In many cases it's enough to only call SetValue() if the (new) value differs from the current value. But it depends on the conditio...

When using sizers there's a parameter for the border width and flags which determine on which side to apply the border.

If you're using a GUI editor, these options should be somewhere, too.

I can't tell you how to do it in formbuilder, but you have to assign a bitmap for the toolbar item. It can't be empty.

I see. Unfortunately as I have a variable number of rows, I end up with a lot of extra space.

Just recalculate the minimum size each time the number of rows changes and do a Layout().

Without having tested it, the most obvious difference is the wxWANTS_CHARS flag that you're using for the derived class. Just deriving from wxScrolledWindow should not make any difference at all.

Do you happen to have a link on how BestSize (and InitialSize) are used by wxWidgets when doing dynamic layouts? Not really, only this: http://docs.wxwidgets.org/trunk/overview_sizer.html But there is not much to know anyway. All controls have 3 sizes that are used by the sizer algorithm: A "b...

I simply don't understand why the sizer isn't taking into account the scrollbar height when it's being laid out. It's not the sizer's fault. wxGrid reports a "best size", that's the size needed to display everything without scrollbars. The problem in your case is that the content fits in ...

Does GetDefaultRowSize() adjust for font size?

Probably not. But if you have so few rows, you can get each individual row height with wxGrid::GetRowSize ( row ).

How many items does the grid typically have? Maybe you can calculate and set a reasonable minimum height based on wxGrid::GetDefaultRowSize().

How about adding the wxALWAYS_SHOW_SB style flag as a workaround?

Can you try to create a small, compilable sample or at least show a screenshot? Probably unrelated, but still worth mentioning: Flags like wxALIGN_LEFT or wxALIGN_RIGHT make no sense in a horizontal(!) boxsizer. In newer wxWidgets version this should have caused an assert. Which wxWidgets version ar...

For clarity, what is the technical difference between SetSizerAndFit() and SetSizer() I think that's pretty well explained in the doc: http://docs.wxwidgets.org/trunk/classwx_window.html#a29938af9828fd35da666536cdfb6b73c ...and is this size information ever communicated to its parent? Not directly....

Ok, that means that the string data already lies UTF8 encoded in memory. This is the actual underlying cause of your problem. But i still don't know how this can happen. If should only happen if the source file is encoded in UTF8, but the compiler ignores this and interprets it as ISO8859-1 (or any ...

Change SetSizerAndFit to SetSizer. //this->SetSizerAndFit(sizer); this->SetSizer(sizer); SetSizerAndFit only makes sense if "this" is a toplevel window like a wxFrame or wxDialog. Although i have to admit that i'm not sure why that leads to a crash, but i was too lazy to research it any fu...

Can you show a memory view of the string literal when you use the wxT() macro?

It should look like this:
