Because on some ports native renderers require a valid reference to the windows be drawn then it is necessary to implement and use new wxPGCellRenderer::DrawCaptionSelectionRect method which passes this additional argument.
SetPropertyTextColour, SetPropertyBackgroundColour methods are able to set colours recursively for sub-properties but SetPropertyColoursToDefault method is not.
For the sake of consistency, SetPropertyColoursToDefault method is extended to have the same capabilities as SetPropertyTextColour and SetPropertyBackgroundColour. Behaviour and signature in default case (no recursion) is preserved.
For internal purposes there were also implemented helper methods in wxPGProperty class: SetDefaultColours, ClearCells.
Horizontal alignment of bitmap associated with wxPGChoice item drawn in wxPGComboBox (in wxPropertyGrid::OnComboItemPaint) needs to be adjusted by 1 pixel (as it is already done for text label) in order to get the bitmap in the same position when wxPGComboBox is selected.
Definitions of non-standard LLONG_MAX, LLONG_MIN and ULLONG_MAX constants are
excluded from MinGW limits.h when compiling in "strict ANSI" mode, so define
them ourselves.
Fixes the bug which could be observed if string containing more then one flag entry was provided to wxPGProperty::SetFlagsFromString. In this case property flags were not set properly (were not set all) due to the error in splitting the string into tokens (whole string instead of its individual token was taken to compare).
Lookup table used to map between flag values and their names is redesigned in order to reduce the size and to make indexing simpler. There are no longer NULL entries in the table and every flag name is identified explicitly by the corresponding flag value and not by the index of the name entry in the table. Thanks to this the relation between flag value and flag name is more clear and the loops in wxPGProperty::GetFlagsAsString/SetFlagsAsString can be simplified.
Currently, customizing some dialogs for small screen environment is done statically on the build stage by setting wxPG_SMALL_SCREEN to 1 (what is done for WXWINCE only).
Instead, we can do this for all platforms in a dynamic manner, based on the classification provided by wxSystemSettings::GetScreenType() function.
In order to do so there is introduced a static helper function wxPropertyGrid::IsSmallScreen() which is used to select right parameters (size, position) for several dialogs in order to display them correctly on the small screen.
When calculating widths of columns in the header there is necessary to take into account also width of the vertical scrollbar in the grid, if it exists. When scrollbar is ignored in calculations then we get wrong width of internal border and in result the columns of the header don't match the columns of the grid (this issue can be observed in the propgrid sample).
Because code responsible for determining widths of all columns is duplicated in OnPageUpdated() and OnColumWidthsChanged() methods it can be moved to the new shared method DetermineAllColumnWidths().
Method DetermineColumnWidth() used now to determine width of the one column only is no longer necessary and can be removed.
This flag shouldn't be used in vertical sizers (in wxLongStringProperty and wxPGArrayEditorDialog) because vertical alignment flags are ignored in such sizers and the assertion message is thrown in wxBoxSizer::DoInsert. This can be observed e.g. in propgrid sample when there is launched wxLongStringProperty or ArrayDoubleProperty editor.
Remove second unnecessary casting from wxWindow to wxTextCtrl and use wxTextCtr::IsEmpty() function to check directly if the text control contains any text instead of examining retrieved string value.
