The SetLayout function changes the layout of a device context (DC).
Syntax
DWORD SetLayout(
[in] HDC hdc,
[in] DWORD l
);
Parameters
[in] hdc
A handle to the DC.
[in] l
The DC layout. This parameter can be one or more of the following values.
| Value | Meaning |
|---|---|
|
Disables any reflection during BitBlt and StretchBlt operations. |
|
Sets the default horizontal layout to be right to left. |
Return value
If the function succeeds, it returns the previous layout of the DC.
If the function fails, it returns GDI_ERROR.
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 in Arabic and Hebrew cultures.
Once the LAYOUT_RTL flag is selected, flags normally specifying right or left are reversed. To avoid confusion, consider defining alternate words for standard flags, such as those in the following table.
| Standard flag | Suggested alternate name |
|---|---|
| WS_EX_RIGHT | WS_EX_TRAILING |
| WS_EX_RTLREADING | WS_EX_REVERSEREADING |
| WS_EX_LEFTSCROLLBAR | WS_EX_LEADSCROLLBAR |
| ES_LEFT | ES_LEAD |
| ES_RIGHT | ES_TRAIL |
| EC_LEFTMARGIN | EC_LEADMARGIN |
| EC_RIGHTMARGIN | EC_TRAILMARGIN |
SetLayout cannot modify drawing directly into the bits of a DIB.
