changes the behaviour of the latter.
@beginStyleTable
- @style{wxBORDER_DEFAULT}:
+ @style{wxBORDER_DEFAULT}
The window class will decide the kind of border to show, if any.
- @style{wxBORDER_SIMPLE}:
+ @style{wxBORDER_SIMPLE}
Displays a thin border around the window. wxSIMPLE_BORDER is the
old name for this style.
- @style{wxBORDER_SUNKEN}:
+ @style{wxBORDER_SUNKEN}
Displays a sunken border. wxSUNKEN_BORDER is the old name for this
style.
- @style{wxBORDER_RAISED}:
+ @style{wxBORDER_RAISED}
Displays a raised border. wxRAISED_BORDER is the old name for this
style.
- @style{wxBORDER_STATIC}:
+ @style{wxBORDER_STATIC}
Displays a border suitable for a static control. wxSTATIC_BORDER
is the old name for this style. Windows only.
- @style{wxBORDER_THEME}:
+ @style{wxBORDER_THEME}
Displays a native border suitable for a control, on the current
platform. On Windows XP or Vista, this will be a themed border; on
most other platforms a sunken border will be used. For more
information for themed borders on Windows, please see Themed
borders on Windows.
- @style{wxBORDER_NONE}:
+ @style{wxBORDER_NONE}
Displays no border, overriding the default border style for the
window. wxNO_BORDER is the old name for this style.
- @style{wxBORDER_DOUBLE}:
+ @style{wxBORDER_DOUBLE}
This style is obsolete and should not be used.
- @style{wxTRANSPARENT_WINDOW}:
+ @style{wxTRANSPARENT_WINDOW}
The window is transparent, that is, it will not receive paint
events. Windows only.
- @style{wxTAB_TRAVERSAL}:
+ @style{wxTAB_TRAVERSAL}
Use this to enable tab traversal for non-dialog windows.
- @style{wxWANTS_CHARS}:
+ @style{wxWANTS_CHARS}
Use this to indicate that the window wants to get all char/key
events for all keys - even for keys like TAB or ENTER which are
usually used for dialog navigation and which wouldn't be generated
the arrows or etc., but would still like to have normal keyboard
navigation take place, you should call Navigate in response to the
key events for Tab and Shift-Tab.
- @style{wxNO_FULL_REPAINT_ON_RESIZE}:
+ @style{wxNO_FULL_REPAINT_ON_RESIZE}
On Windows, this style used to disable repainting the window
completely when its size is changed. Since this behaviour is now
the default, the style is now obsolete and no longer has an effect.
- @style{wxVSCROLL}:
+ @style{wxVSCROLL}
Use this style to enable a vertical scrollbar. Notice that this
style cannot be used with native controls which don't support
scrollbars nor with top-level windows in most ports.
- @style{wxHSCROLL}:
+ @style{wxHSCROLL}
Use this style to enable a horizontal scrollbar. The same
limitations as for wxVSCROLL apply to this style.
- @style{wxALWAYS_SHOW_SB}:
+ @style{wxALWAYS_SHOW_SB}
If a window has scrollbars, disable them instead of hiding them
when they are not needed (i.e. when the size of the window is big
enough to not require the scrollbars to navigate it). This style is
currently implemented for wxMSW, wxGTK and wxUniversal and does
nothing on the other platforms.
- @style{wxCLIP_CHILDREN}:
+ @style{wxCLIP_CHILDREN}
Use this style to eliminate flicker caused by the background being
repainted, then children being painted over them. Windows only.
- @style{wxFULL_REPAINT_ON_RESIZE}:
+ @style{wxFULL_REPAINT_ON_RESIZE}
Use this style to force a complete redraw of the window whenever it
is resized instead of redrawing just the part of the window
affected by resizing. Note that this was the behaviour by default
@endStyleTable
@beginExtraStyleTable
- @style{wxWS_EX_VALIDATE_RECURSIVELY}:
+ @style{wxWS_EX_VALIDATE_RECURSIVELY}
By default, Validate/TransferDataTo/FromWindow() only work on
direct children of the window (compatible behaviour). Set this flag
to make them recursively descend into all subwindows.
- @style{wxWS_EX_BLOCK_EVENTS}:
+ @style{wxWS_EX_BLOCK_EVENTS}
wxCommandEvents and the objects of the derived classes are
forwarded to the parent window and so on recursively by default.
Using this flag for the given window allows to block this
propagation at this window, i.e. prevent the events from being
propagated further upwards. Dialogs have this flag on by default.
- @style{wxWS_EX_TRANSIENT}:
+ @style{wxWS_EX_TRANSIENT}
Don't use this window as an implicit parent for the other windows:
this must be used with transient windows as otherwise there is the
risk of creating a dialog/frame with this window as a parent which
would lead to a crash if the parent is destroyed before the child.
- @style{wxWS_EX_PROCESS_IDLE}:
+ @style{wxWS_EX_PROCESS_IDLE}
This window should always process idle events, even if the mode set
by wxIdleEvent::SetMode is wxIDLE_PROCESS_SPECIFIED.
- @style{wxWS_EX_PROCESS_UI_UPDATES}:
+ @style{wxWS_EX_PROCESS_UI_UPDATES}
This window should always process UI update events, even if the
mode set by wxUpdateUIEvent::SetMode is
wxUPDATE_UI_PROCESS_SPECIFIED.
