QuickWin Function: Returns the properties of the current window.

(Output) Derived type windowconfig. Contains window properties. The windowconfig derived type is defined in IFQWIN.F90 as follows: TYPE windowconfig INTEGER(2) numxpixels ! Number of pixels on x-axis INTEGER(2) numypixels ! Number of pixels on y-axis INTEGER(2) numtextcols ! Number of text columns available INTEGER(2) numtextrows ! Number of text rows available INTEGER(2) numcolors ! Number of color indexes INTEGER(4) fontsize ! Size of default font. Set to ! QWIN$EXTENDFONT when specifying ! extended attributes, in which ! case extendfontsize sets the ! font size CHARACTER(80) title ! The window title INTEGER(2) bitsperpixel ! The number of bits per pixel INTEGER(2) numvideopages ! Unused INTEGER(2) mode ! Controls scrolling mode INTEGER(2) adapter ! Unused INTEGER(2) monitor ! Unused INTEGER(2) memory ! Unused INTEGER(2) environment ! Unused ! ! The next three parameters provide extended font attributes. ! CHARACTER(32) extendfontname ! The name of the desired font INTEGER(4) extendfontsize ! Takes the same values as fontsize, ! when fontsize is set to ! QWIN$EXTENDFONT INTEGER(4) extendfontattributes ! Font attributes such as bold ! and italic END TYPE windowconfig |
The result type is LOGICAL(4). The result is .TRUE. if successful; otherwise, .FALSE. (for example, if there is no active child window).
GETWINDOWCONFIG returns information about the active child window. If you have not set the window properties with SETWINDOWCONFIG, GETWINDOWCONFIG returns default window values.
A typical set of values would be 1024 x pixels, 768 y pixels, 128 text columns, 48 text rows, and a font size of 8x16 pixels. The resolution of the display and the assumed font size of 8x16 pixels generates the number of text rows and text columns. The resolution (in this case, 1024 x pixels by 768 y pixels) is the size of the virtual window. To get the size of the physical window visible on the screen, use GETWSIZEQQ. In this case, GETWSIZEQQ returned the following values: (0,0) for the x and y position of the physical window, 25 for the height or number of rows, and 71 for the width or number of columns.
The number of colors returned depends on the video drive. The window title defaults to "Graphic1" for the default window. All of these values can be changed with SETWINDOWCONFIG.
Note that the bitsperpixel field in the windowconfig derived type is an output field only, while the other fields return output values to GETWINDOWCONFIG and accept input values from SETWINDOWCONFIG.
!Build as QuickWin or Standard Graphics App.
