The Color control is added to the interface.
Attaching Button Toggles
Next, attach a button to toggle the vidFormat. Since the 0 and 1 settings are not very
intuitive for the video format selection, create buttons labeled “NTSC” and “PAL.” The
following examples show two ways to attach a button toggle.
To attach a button toggle:
1 Create a directory called icons/ux in your $HOME/nreal directory:
mkdir -p $HOME/nreal/icons/ux
2 Copy all of the icons that begin with vr_ from doc/html/cook/macro_icons to your
$HOME/nreal/icons/ux directory. There are a total of eight files.
When clicked, the first button toggles between PAL (vr_pal.off.nri) and NTSC
(vr_ntsc.off.nri). Two additional buttons, vr_pal.off.focus.nri and vr_ntsc.off.focus.nri,
indicate when the pointer is over the button. These are called focus buttons. To view
the code, see “
Using Parameters Controls Within Macros ” on page 379.
3 To add the toggle button function, edit the VidResizeUI.h file:
nuiPushMenu(“Tools”);
nuiPushToolBox(“Transform”);
nuiToolBoxItem(“@VidResize”,VidResize());
nuiPopToolBox();
nuiPopMenu();
nuxDefExprToggle(“VidResize.keepAspect”);
nuiPushControlGroup(“VidResize.Background Color”);
nuiGroupControl(“VidResize.bgRed”);
nuiGroupControl(“VidResize.bgGreen”);
nuiGroupControl(“VidResize.bgBlue”);
nuiPopControlGroup();
nuiPushControlWidget(“VidResize.Background Color”,
nuiConnectColorTriplet(kRGBToggle,kCurrentColor,1)
);
nuxDefExprToggle(“VidResize.vidFormat”,
“ux/vr_ntsc.off.nri|ux/vr_ntsc.off.focus.nri”,
“ux/vr_pal.off.nri|ux/vr_pal.off.focus.nri”
);
