SetLayout (Windows CE 5.0)
This function changes the layout of a device context (DC).
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 Values
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.
| 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 |
