I'm making an application in Win32 API that uses the modern Ribbon style UI. I've successfully tested an SampleRibbon program. The only problem I'm having is that, How to detect the X and Y coordinates of the Ribbon bar? When I draw a control at (0,0) it gets hidden behind the Ribbon bar. But I don't want it to be hidden behind the bar. Is there any function to get the coordinates of the Ribbon bar so that I can draw the control automatically below the Ribbon.
The function you're looking for is IUIRibbon::GetHeight.

I would like to create an app that intercepts the mouse coordinates and modify them.
I want to build an app that runs in the background and intercepts the mouse movement, filtering it, for all apps running on macOS.
Suppose the mouse is scrolling freely but if the user presses a global shortcut, like CMD ALT X, the vertical scrolling is filtered and just the horizontal scrolling passes to macOS.
First question: what should I use to do that? Just point me in the right direction if the topic is too extensive.
Second question: is that possible to do for a sandbox app?
How do I add Undetermined Progress Bar in win32 api?
I just want the animation/progress bar to display as a child to main window when a button is press, continue animation until the the button is again played and then dissapear.
The standard Win32 ProgressBar control has a Marquee mode for that exact purpose.
Perhaps you just wish to show a small dialog containing an animated GIF file. You'll find plenty of example GIFs on the Internet.

I have an MFC dialog (actual a dialog bar with in a dialog) that contains a progress bar with these strange black pixels in the corner. I have tried the following to remove them:
Change most of the border type styles and the transparent style of the control.
Override the OnEraseBkgnd in a class derived a CProgressCtrl.
Setting the background color of the control by PBM_SETBKCOLOR.
I have yet to find a way to remove these black pixel.
Here is an example of what it looks like:
It seems I have found the issue. When the progress bar performs its painting it was sending an WM_ERASEBKGND message to the dialog to get the background with which it would paint. Some how the DC brush origin was being messed up. Using the following code at the start of the function seems to have fixed the issue with no ill effects.
CRect rcClip;
pDC->GetClipBox(rcClip);
pDC->SetBrushOrg(-rcClip.left, -rcClip.top);
I've seen this occur when using ActiveX controls inside control containers that don't have a a window or proper Device Contexts (The VB6 frame control is one of these) but I'm not sure if the same problem applies to MFC windows and controls though.
Try making the control parent a normal static window.

User can eject and withdraw right portion of window with a button.
Update: How to draw the vertical line in the tool bar?
This is actually part of the window. When you click the button, the window and view just resize into their appropriate positions.
Check out NSViewAnimation.
I am trying to create an interface for my application using Qt Designer. I want it to have a tabbed, ribbon-style set of controls at the top, and a MDI-style area with docked windows which I plan to show and hide depending on which tab of the ribbon is currently selected. I am just beginning with Qt Designer as well as Qt4 itself for that matter so I'm not quite sure how to setup the window, which widgets and layouts should I use etc.
It's quite obvious there should be a QTabWidget at the top, but I'm not sure about the bottom. Should I use a QFrame? A QMdiArea? A dock widget? What layouts can I use to make sure the tab widget has a fixed height, occupies the whole width of the window at all times and the bottom area scales as the window is resized?
I've read in the manual that splitter layouts allow for manual adjustment of the size of the widgets they contain, but I can't drag the box size of a widget after I place them inside a splitter. Thus I'm unable to setup the area below the ribbon. Anyone, help?
You should look into the QMainWindow and check the multiple utilities it can provide you (Toolbar, StatusBar, DockWidgets, CentralWidget, etc...).
The way I understood your case is that you will always have the MDI Area visible, and that the tab bar will only be used to change the dockWidgets. Here's how I would do it.
The centralWidget of the mainWindow would be a QWidget with a QVBoxLayout containing a QTabBar widget first (up) and a QMdiArea under it. The sizes should be handled automatically.
This will allow the user (or you) to dock widgets on the left, bottom, top or right areas of the mainWindow's central widget. Keep pointers to the dockWidgets to be able to move and show/hide them at will.
Hope this helps.
VTK Designer, which is built on Qt, has a Ribbon-ish interface. You might take a look at the source code for reference.
