static void AddUserAttributes(CGXStylesMap* stylesMap);
stylesMap
Points to the styles-map object.
Call this static method to register user attributes with the styles-map. Registered user attributes will be displayed in the CGXStyleSheet and can be modified by the user with the style sheet.
If you don’t want the attributes to be visible in the CGXStyleSheet, you should not call AddUserAttributes. You will still be able to use user attributes in your grid. They will only be hidden from the user in the CGXStyleSheet.
CGXDateTimeCtrl needs some user attributes that specify the behavior of the date/time control. These need to be specified for the control to be able to display itself in the required format. This call will add all the user attributes required for this control.
This snippet shows how the user attributes are added:
void CGXDateTimeCtrl::AddUserAttributes(CGXStylesMap* pStylesMap)
{
pStylesMap->AddUserAttribute(GX_IDS_UA_DATENOEDIT);
pStylesMap->AddUserAttribute(GX_IDS_UA_DATEMIN);
pStylesMap->AddUserAttribute(GX_IDS_UA_DATEMAX);
pStylesMap->AddUserAttribute(GX_IDS_UA_DATEVALIDMODE);
pStylesMap->AddUserAttribute(GX_IDS_UA_DATEFORMATTYPE);
pStylesMap->AddUserAttribute(GX_IDS_UA_CUSTOMFORMAT);
}
Here is a brief explanation of what each attribute stands for and how you can use these attributes to change every aspect of the CGXDateTimeCtrl.
·GX_IDS_UA_DATENOEDIT: This user attribute specifies which of the control attributes are editable
enum NoEdit
{
FixedYear = 0x0001,// The year is non-editable
FixedMonth = 0x0002,// The month is non-editable
FixedDay = 0x0004,// The day is non-editable
FixedHour = 0x0008,// The hour is non-editable
FixedMinute = 0x0010,// The minute is non-editable
FixedSecond = 0x0020// The second is non-editable
};
Each of the gadgets can be made editable or non-editable by changing these attributes.
·GX_IDS_UA_DATEMIN and GX_IDS_UA_DATEMAX: These user attributes are used to specify the minimum and maximum valid dates, which will be enforced by the control when the user enters data.
Example values for these attributes:
//The maximum allowed date
CString strMax(_T("3/2/72"));
CString strMin(_T("3/2/52"));
You can then set these values on the style for the date control cell like this
SetStyleRange(CGXRange(8,1),
CGXStyle()
.SetControl(GX_IDS_CTRL_DATETIME)
.SetUserAttribute(GX_IDS_UA_DATEFORMATTYPE, str)
.SetValue(dt.Format())
.SetUserAttribute(GX_IDS_UA_DATEMAX, strMax)
.SetUserAttribute(GX_IDS_UA_DATEMIN, strMin)
.SetUserAttribute(GX_IDS_UA_DATEVALIDMODE, strValidate)
);
?GX_IDS_UA_DATEVALIDMODE: This user attribute specifies the validation mode for the cell. This will be of type ValidationMode
// The validation types as used by Get/SetMinMax
enum ValidationMode
{
NoValidation,// No validation is required
TimeValidation,// Validation of time fields only
DateValidation,// Validation of date fields only
DateTimeValidation// Validation of date & time fields
};
This can be set to any of the above values. The following ids representing the above are already defined in the grid header files
// The validation types as used by GX_IDS_UA_DATEVALIDMODE
GX_DTVALIDMODE_NONE_T("0")// No validation is required
GX_DTVALIDMODE_TIME_T("1")// Validation of time fields only
GX_DTVALIDMODE_DATE_T("2")// Validation of date fields only
GX_DTVALIDMODE_DATETIME_T("3")// Validation of date & time fields
·GX_IDS_UA_DATEFORMATTYPE: This attribute sets the format for the CGXDateTimeCtrl. The format essentially specifies the layout of the various gadgets in the control. For example a format of say, CGXBDateTimeCtrl::Time would set up the gadgets in the control in such a way that time is displayed in the control.
The following are the predefined constants for the formats:
GX_DTFORMAT_TIME_T("0")// Locale time format
GX_DTFORMAT_SHORTDATE_T("1")// Locale short date format
GX_DTFORMAT_LONGDATE_T("2")// Locale long date format
GX_DTFORMAT_CUSTOM_T("3")// A user supplied date/time format string
CGXDateTimeCtrl also supports custom formats.
Here is how custom formats are specified:
hHours
hh Hours with leading zero
H Same as h, but 24-hour format
HH Same as hh, but 24-hour format
m Minutes
mm Minutes with leading zero
s Seconds
ss Seconds with leading zero
t Abbreviated AM/PM designator
tt Full AM/PM designator
dNumeric day
ddNumeric day with leading zero
dddAbbreviated day name
ddddFull day name
MMonth
MMMonth with leading zero
MMMAbbreviated month
MMMM Full month name
YYear without century
yyYear with leading zero, without century
yyyyYear including century
ggEra (ignored)
'text' Quoted text passed straight through
Any combination of these can be coded into the user attribute, GX_IDS_UA_CUSTOMFORMAT to give a totally custom appearance to the CGXDateTimeCtrl.
·GX_IDS_UA_FASTINPUT: This attribute sets the fast input mode for the datetime control. If this attribute is equal to1, fast input will be enabled. With Fast Input, the input foccus will automatically move to the next gadget while the user is entering numbers.
The following are the predefined constants for the formats:
CGXAbstractControlFactory::RegisterAllUserAttributes CGXStylesMap::AddUserAttribute
