      sizeof in class org.lwjgl.system.Struct<DEVMODE>

    • dmDeviceName

      public ByteBuffer dmDeviceName()
      A zero-terminated character array that specifies the "friendly" name of the printer or display; for example, "PCL/HP LaserJet" in the case of PCL/HP LaserJet. This string is unique among device drivers. Note that this name may be truncated to fit in the dmDeviceName array.

    • dmDeviceNameString

      public String dmDeviceNameString()
      A zero-terminated character array that specifies the "friendly" name of the printer or display; for example, "PCL/HP LaserJet" in the case of PCL/HP LaserJet. This string is unique among device drivers. Note that this name may be truncated to fit in the dmDeviceName array.

    • dmSpecVersion

      public short dmSpecVersion()
      the version number of the initialization data specification on which the structure is based. To ensure the correct version is used for any operating system, use GDI32.DM_SPECVERSION.

    • dmDriverVersion

      public short dmDriverVersion()
      the driver version number assigned by the driver developer

    • dmSize

      public short dmSize()
      specifies the size, in bytes, of the DEVMODE structure, not including any private driver-specific data that might follow the structure's public members. Set this member to SIZEOF to indicate the version of the DEVMODE structure being used.

    • dmDriverExtra

      public short dmDriverExtra()
      contains the number of bytes of private driver-data that follow this structure. If a device driver does not use device-specific information, set this member to zero.

    • dmFields

      public int dmFields()
      specifies whether certain members of the DEVMODE structure have been initialized. If a member is initialized, its corresponding bit is set otherwise the bit is clear. A driver supports only those DEVMODE members that are appropriate for the printer or display technology.

    • dmDisplayOrientation

      public int dmDisplayOrientation()
      for display devices only, the orientation at which images should be presented. If GDI32.DM_DISPLAYORIENTATION is not set, this member must be zero. If GDI32.DM_DISPLAYORIENTATION is set, this member must be one of the following values:
      GDI32.DMDO_DEFAULT, GDI32.DMDO_90, GDI32.DMDO_180, GDI32.DMDO_270

      To determine whether the display orientation is portrait or landscape orientation, check the ratio of dmPelsWidth to dmPelsHeight.

    • dmDisplayFixedOutput

      public int dmDisplayFixedOutput()
      for fixed-resolution display devices only, how the display presents a low-resolution mode on a higher-resolution display. For example, if a display device's resolution is fixed at 1024 x 768 pixels but its mode is set to 640 x 480 pixels, the device can either display a 640 x 480 image somewhere in the interior of the 1024 x 768 screen space or stretch the 640 x 480 image to fill the larger screen space. If GDI32.DM_DISPLAYFIXEDOUTPUT is not set, this member must be zero. If GDI32.DM_DISPLAYFIXEDOUTPUT is set, this member must be one of the following values:
      GDI32.DMDFO_DEFAULT, GDI32.DMDFO_CENTER, GDI32.DMDFO_STRETCH

      public int dmNup()
      for printer devices only

    • dmDisplayFrequency

      public int dmDisplayFrequency()
      specifies the frequency, in hertz (cycles per second), of the display device in a particular mode. This value is also known as the display device's vertical refresh rate.

      When you call the User32.EnumDisplaySettingsEx(java.nio.ByteBuffer, int, org.lwjgl.system.windows.DEVMODE, int) function, the dmDisplayFrequency member may return with the value 0 or 1. These values represent the display hardware's default refresh rate. This default rate is typically set by switches on a display card or computer motherboard, or by a configuration program that does not use display functions such as ChangeDisplaySettingsEx.
