SetLayout (Windows Embedded CE 6.0)
1/6/2010
This function changes the layout of a device context (DC).
Syntax
DWORD SetLayout(
HDC hdc,
DWORD dwLayout,
);
Parameters
- hdc
[in] Handle to the DC.
dwLayout
[in] Specifies the DC layout. This parameter can be a combination of one or more of the following flags.Flag Description LAYOUT_BITMAPORIENTATIONPRESERVED
Not supported.
LAYOUT_RTL
Sets the default horizontal layout to be right-to-left.
If the layout of your DC is currently right-to-left and you want to change it to left-to-right, set dwLayout to 0x00.
Return Value
If the function succeeds, it returns the previous layout of the DC. A return value of 0 indicates a left-to-right layout.
If the function fails, it returns GDI_ERROR. To get extended error information, call GetLastError.
Remarks
The layout specifies the order in which text and graphics are revealed in a window or a device context. The default is left-to-right. The SetLayout function changes this to be right-to-left, which is the standard layout in Arabic and Hebrew cultures.
The SetLayout function cannot modify drawing directly into the bits of a DIB.
After the LAYOUT_RTL flag is selected, flags that normally specify right or left are reversed. To avoid confusion, consider defining alternate words for standard flags, such as those in the following table.
