Data Type

Description

bBrowserColumn:CaptionSortMarker defines the sort marker in the column caption.

CaptionSortMarker

The exact appearance of the sort marker is dependent on the windows operating system.

The values below are supported:

Value	Description
BDCF_SORTMARKER_NONE	No sort marker.
BDCF_SORTMARKER_UP	Marker for ascending sort order.
BDCF_SORTMARKER_DOWN	Marker for descending sort order.

Remarks

So that sort markers are shown in the bBrowser, the method bBrowser:EnableCaptionSortMarker() must be invoked before.

So that changes at this access are also shown in the bBrowser, the column caption must be redrawn with the method bBrowser:Redraw(). This is only necessary if the column is inside the visible area of the bBrowser.

Samples

In the sample below a bBrowser control is created in which a sort marker is defined in the column caption for the field LASTNAME.

LOCAL odbsCUSTOMER AS DBServer
LOCAL oBrowser     AS bBrowser
LOCAL oColumn      AS bDataColumn

// Create a bBrowser
odbsCUSTOMER := DBServer{"CUSTOMER"}
odbsCUSTOMER:SetOrder("NAME")

oBrowser := bBrowser{oOwner,;
                     1000,;
                     Point{0, 0},;
                     Dimension{300, 250}}

// Set server in bBrowser and show it
oBrowser:Use(odbsCUSTOMER)
oBrowser:Show()

// Define sort marker in column LASTNAME
oColumn := oBrowser:GetColumn(#LASTNAME)
oColumn:CaptionSortMarker := BDCF_SORTMARKER_UP

// Importand!!!
// -> Redraw bBrowser
oBrowser:Redraw(#CAPTION)
