|
|
wxSpinCtrlDbl is a double valued wxSpinCtrl using non native (wxWidgets) widgets
|
|
|
|
It consists of a wxSpinButton and a wxTextCtrl on a wxControl and can be used
|
|
as a drop in replacement for the wxSpinCtrl. It's been tested in GTK and MSW
|
|
and should work with MAC, but you may need to fix the sizing perhaps. It
|
|
will not work in Motif as there is no wxSpinButton in Motif.
|
|
|
|
Differences to wxSpinCtrl:
|
|
|
|
It remembers the initial value as a default value, call SetDefaultValue,
|
|
or press <ESC> to return to it
|
|
|
|
Shift + Arrow = *2 increment value
|
|
Ctrl + Arrow = *10 increment value
|
|
Alt + Arrow = *100 increment value
|
|
combinations of Shift, Ctrl, Alt increment by the product of the factors
|
|
|
|
PgUp & PgDn = *10 increment * the product of the Shift, Ctrl, Alt factors
|
|
|
|
<SPACE> sets the control's value to the it's last valid state
|
|
|
|
SetDigits controls the format of the text, # decimal places
|
|
exponential uses the %.Xle format otherwise %.Xlf, where places = X
|
|
for arbitray formats subclass control and override SyncSpinToText()
|
|
for proper behavior when a user types in a value
