W_INFO and %W_INFO routines for information on retrieving other types of window information
You can combine %U_WINMETRICS subfunctions to perform additional calculations. For example, the following code displays the size of the screen in characters. It does this by dividing the pixel size of the screen by the size of a character. (Note that this calculation doesn’t account for toolbars or scrollbars.)
xcall U_MESSAGE(“width “ + %string(%U_WINMETRICS(D_SCREEN_X)/ & %U_WINMETRICS(D_CHARWIDTH, my_window))) ;Screen width in characters xcall U_MESSAGE(“height “ + %string(%U_WINMETRICS(D_SCREEN_Y)/ & %U_WINMETRICS(D_CHARHEIGHT, my_window)));Screen height in characters
For a more complete example, see Get_Window_Size, available from Synergy CodeExchange in the Synergex Resource Center. This example calculates the available area in a window (with some exceptions) when that window is fully expanded.
return = %U_WINMETRICS(D_CHARHEIGHT, window_id)

Discussion
The D_CHECKBOX_X subfunction of %U_WINMETRICS returns the width of a check box or radio button in pixels.
Examples
The following example returns in pixel_width (i4) the width of a check box in pixels.
pixel_width = %U_WINMETRICS(D_DCHECKBOX_X)
return = %U_WINMETRICS(D_CLIENT_RECT, h_wnd, rect)
or
xcall U_WINMETRICS(D_CLIENT_RECT, h_wnd, rect)
Return value
return
On Windows, true if successful, or false if not. (^VAL)
Arguments
h_wnd
The handle for the window whose client area coordinates you want to retrieve. This doesn’t need to be a Synergy window. For example, this could be the handle for an ActiveX control, a window created by a DLL, or a window created by a different process. (n)
rect
The returned rectangle coordinates for the client area of the window. Rect is returned as a group of four i4 values, which are coordinates for the left, top, right, and bottom points (respectively) of the client area. (n)
The D_CLIENT_RECT subfunction of %U_WINMETRICS returns coordinates for the client area of the h_wnd window. (The client area is the inside area of a window minus the frame, captions, information line, and footer.) These coordinates are returned in the rect argument, which is a group of i4 values for the left, top, right, and bottom points of the client area. The left and top coordinates are always zero.
D_CLIENT_RECT and D_VISIBLE_RECT will always be equal for the application window (WID_APP), and they will always be equal for the container window (ID_CONTAINTER).
For the application and container windows, however, D_CLIENT_RECT may not be equal if, for example, a toolbar is placed. This area would be excluded from D_CLIENT_RECT for the application window.
For any other Synergy window, D_CLIENT_RECT and D_VISIBLE_RECT will be equal if the window does not include buttons.
Examples
The following example gets the client rectangle for the application window in rect.
success = %U_WINMETRICS(D_CLIENT_RECT, %W_INFO(WIF_HWND, WID_APP), rect)

Arguments
window_id
The window ID or one of the following: (n)
The application window (excluding border and caption).
The container window for the Synergy application (including the border and caption).
col_num
If D_SIZE is passed, col_num specifies the number of columns whose width you want to measure. If D_POSITION is passed, col_num specifies a column number. (n)
D_SIZE
(optional) Return the pixel width of the number of columns specified in col_num. (default) (n)
D_POSITION
(optional) Return the x-axis pixel coordinate for the right side of the column specified by col_num. (n)
Discussion
The D_COLTOX subfunction of %U_WINMETRICS returns either a width or an x-axis pixel coordinate.
- If D_SIZE is passed (or neither D_SIZE nor D_POSITION is passed), D_COLTOX returns the width in pixels of the number of columns specified in col_num.
- If D_POSITION is passed, D_COLTOX returns an x-axis (horizontal) pixel coordinate for the right side of the column specified by col_num. This value is based on the display area origin, a coordinate system in which the 0, 0 pixel is at the top left of the display area.
Examples
This example returns in pixel_width (i4) the number of pixels that equates to six columns for wndid.
pixel_width = %U_WINMETRICS(D_COLTOX, wndid, 6, D_SIZE)
This example returns in pixel_width the right-most pixel of column 25 in the application window.
pixel_width = %U_WINMETRICS(D_COLTOX, WID_APP, 25, D_POSITION)
return = %U_WINMETRICS(D_EDITEXTRA_X)
Return value
return
On Windows, the extra pixel width required for an edit control. (^VAL)
Discussion
The D_EDITEXTRA_X subfunction of %U_WINMETRICS returns the extra pixel width required for an edit control to be placed over a specific set of characters. This is in addition to the number of characters times the character width.
Examples
The following example returns in pixel_width (i4) the number of extra pixels required for an edit control.
pixel_width = %U_WINMETRICS(D_EDITEXTRA_X)
return = %U_WINMETRICS(D_HSCROLL_Y)
Return value
return
On Windows, the height of a horizontal scroll bar in pixels. (^VAL)
Discussion
The D_HSCROLL_Y subfunction of %U_WINMETRICS returns the height of a horizontal scroll bar in pixels.
Examples
The following example returns in pixel_height (i4) the height of a horizontal scroll bar in pixels.
pixel_height = %U_WINMETRICS(D_HSCROLL_Y)
return = %U_WINMETRICS(D_MAPPOINTS, h_from, h_to, x_y_pair)
or
xcall U_WINMETRICS(D_MAPPOINTS, h_from, h_to, x_y_pair)
Return value
return
On Windows, a 32-bit value that contains the addends used to convert coordinates. The low-order 16 bits contain the x-axis addend, and the high-order 16 bits contain the y-axis addend. Each value can be a negative number. (See the Discussion below for information on extracting these values.) (^VAL)
Arguments
h_from
A handle for the window whose coordinate system you want x_y_pair converted from. (n)
h_to
A handle for the window whose coordinate system you want x_y_pair converted to. (n)
x_y_pair
A set (or sets) of coordinates (x, y) for a point (or points) in the h_from window. Each 8 bytes of this argument is interpreted as a pair of i4 values that represent x- and y- axis coordinates, so the value you pass must have a size that’s a multiple of 8 bytes (8 bytes for a single point, 16 bytes for two points, and so forth). The converted coordinates are returned in this argument, so it must be writable. (n)
The D_MAPPOINTS subfunction of %U_WINMETRICS converts the x_y_pair set (or sets) of coordinates from the coordinate system of the h_from window to the coordinate system of the h_to window. In other words, it converts coordinates that are relative to the upper-left corner of the h_from window to coordinates that are relative to the upper-left corner of the h_to window. (Note that these windows can be in different processes.) This could be useful, for example, if you have an ActiveX control that has no border and acts as a background or pointer within a larger window. When a user clicks on the control, your event routine may need to convert the coordinates of the click location to coordinates in the same location in the parent window.
The converted coordinates are returned in the x_y_pair argument in the same order they were passed.
The addends used to calculate the new set(s) of coordinates are returned in return, which is a 32-bit value. The low-order 16 bits contain the x-axis addend, and the high-order 16 bits contain the y-axis addend. For example, if h_from is a window positioned at 100, 200 and h_to is a window positioned at 500, 50, return will contain the x-axis addend (decimal 400, hex190) in the low-order word and the y-axis addend (decimal -150, hex FF6A in 16-bit twos complement) in the high-order word. In this case, return will be returned as FF6A0190.
To extract the x- and y-axis addends from return, use the following:
cx = rval .band. ^x(FFFF) cy = (rval .band. ^x(FFFF0000)) / ^x(1000)
where cx (i2 or i4) is the addend used to calculate the x-axis coordinates, cy (i2 or i4) is the addend used to calculate the y-axis coordinates, and rval (i4) is the returned value (return). (Rval can be a group of cx, i2 and cy, i2 values on little endian architectures.)
Examples
The following example first gets the visible rectangle for wndid, and then converts these points to their corresponding values in the application window.
if (%U_WINMETRICS(D_VISIBLE_RECT, wndid, rect)) then pts = %U_WINMETRICS(D_MAPPOINTS, %W_INFO(WIF_HWND, wndid), & %W_INFO(WIF_HWND, WID_APP), rect)

pixel_height = %U_WINMETRICS(D_ROWTOY, WID_APP, 17, D_POSITION)
return = %U_WINMETRICS(D_SCALE)
Return value
return
On Windows, the display scaling factor. (^VAL)
Discussion
The D_SCALE subfunction of %U_WINMETRICS returns the Windows display scaling factor (percentage) that is in effect on a Windows machine. The display scaling factor is set by the following Windows setting for the monitor that Windows uses as the primary monitor:
Display > Scale and layout > Change the size of text, apps, and other items
For example, if 100 is returned for D_SCALE, the Windows display scaling factor is set to 100%. You can use this information to help make sizing decisions when converting pixels to characters, when sizing window borders, etc.

Discussion
The D_XTOCOL subfunction of %U_WINMETRICS returns the number of the column that contains the pixel whose x-axis coordinate is x_value in the window specified by window_id. This subfunction assumes x_value is based on the display area origin, a coordinate system in which the 0, 0 pixel is at the top left of the display area.
When using proportional fonts in conjunction with D_XTOCOL, the returned column value may not be correct. This value is based on the sizing character for the window, not any actual text.

The following example returns in offset (i4) the number of pixels between the first visible row and the top of the client area for wndid.
offset = %U_WINMETRICS(D_YORIGIN, wndid)
return = %U_WINMETRICS(D_YTOROW, window_id, y_value)
Return value
return
On Windows, the number of the row that contains a given y-axis (vertical) coordinate for a pixel. (^VAL)
Arguments
window_id
The window ID or one of the following: (n)
The application window (excluding border and caption).
The container window for the Synergy application (including the border and caption).
y_value
The y-axis (vertical) coordinate for a pixel. This number must be based on the display area origin (where the 0,0 pixel is at the top left of the display area). (n)
Discussion
The D_YTOROW of %U_WINMETRICS subfunction returns the number of the row that contains the pixel whose y-axis coordinate is y_value in the window specified by window_id. This subfunction assumes y_value is based on the display area origin, a coordinate system in which the 0, 0 pixel is at the top left of the display area.
Examples
The following example returns in row_num (i4) the row number that contains the specified pixel for wndid.
row_num = %U_WINMETRICS(D_YTOROW, wndid, ypos)
