How should I implement sub-windows in my OpenGL viewport? Inside my viewport, I want to reserve some space on the left for labels, and some space around the edges as a border. I've got all the coordinates figured out and everything is displaying properly. My problem is clipping the things in one subwindow that are spilling over into the others. I can't seem to figure out what the OpenGL 3.3, core context way of doing things is. Is it to
use per-vertex clipping?
a scissor test?
a stencil test?
associate a framebuffer with different parts of my window?
Which commands should I be looking at?
Before I spend time writing a full answer, I would like you to confirm that this is what you were describing in your original question:
*---------------------------------------*

A = Labels
B = Main Window
C = Border

According to my assignment admin must be able to create Polls with Questions (create, delete, update) and Choices related to this questions. All of this should be displayed and changable on the same admin page.

Ok, it's not a problem to display one level of nesting like so on
class QuestionInline(admin.StackedInline):
model = Question
class PollAdmin(ModelAdmin):
inlines = [
QuestionInline,

But how to do to get the required poll design structure?
Check out this library it should provide the functionality.
The problem is the following:
Let's consider 2 sets of images embedded in a PowerBI file .pbix:
Set 1: Img1, Img2
Set 2: Img3, Img4, Img5, Img6
For each combination of 2 images between the two sets, we want to set an action (to a bookmark) to display a corresponding visual.
So here, we have these combinations:
(Img1, Img3) -> display Viz1.3
(Img1, Img4) -> display Viz1.4
(Img1, Img5) -> display Viz1.5
(Img1, Img6) -> display Viz1.6
(Img2, Img3) -> display Viz2.3
(Img2, Img4) -> display Viz2.4
(Img2, Img5) -> display Viz2.5
(Img2, Img6) -> display Viz2.6
Let's suppose that we have selected (Img1, Img3) and then we select (click) Img2.
How can we keep the selection on Img3 in order to display Viz2.3 ?

Each image can, I'm pretty sure, only trigger one bookmark. If I'm reading right, I think you need to duplicate the images and hide/show according to the state of the display.
For example in the example above, if the display is Viz1.3 and you click image 2, the updates would be to the viz and to the images in set 2:
Viz1.3 -> Viz2.3
Img3.1 -> Img3.2
Img4.1 -> Img4.2
Img5.1 -> Img5.2
Img6.1 -> Img6.2
And if you updated from there by clicking Img4 to get to Viz2.4, you'd have to update the images in set one
Viz2.3 -> Viz2.4
Img1.3 -> Img1.4
Img2.3 -> Img2.4
So, ultimately, you'd need four version of each image in set one (one for each in set two) and two of each in set two (to match set one). And though you're only showing 6 at any given time, that's 16 which is twice as many as you have visuals. But if you have to have it that way for UX, then I can't think of another way to do it.
| Image | Bookmark |
|-----------|--------------|
| Img1.3 | Viz1.3 |
| Img1.4 | Viz1.4 |
| Img1.5 | Viz1.5 |
| Img1.6 | Viz1.6 |
| Img2.3 | Viz2.3 |
| Img2.4 | Viz2.4 |
| Img2.5 | Viz2.5 |
| Img2.6 | Viz2.6 |
| Img3.1 | Viz1.3 |
| Img3.2 | Viz2.3 |
| Img4.1 | Viz1.4 |
| Img4.2 | Viz2.4 |
| Img5.1 | Viz1.5 |
| Img5.2 | Viz2.5 |
| Img6.1 | Viz1.6 |
| Img6.2 | Viz2.6 |
Showing or hiding bookmarks by screen state
I am creating a listview with 5 columns in Gtk+ using C++. I was able to do that. But the problem is, I need subcolumns for the 2nd column which I'm not sure how to proceed.
firstcolumn | second column | third |
|SC1 | SC2 | SC3| |
| | | | |
Is this possible? Can you suggest how to go about it?
I am trying to draw the intersection of one blue rectangle and one yellow rectangle
,-------------------,
| |
| Blue |
| ,-------+---------,
| | Green | |
'-----------+-------, Yellow |
|_________________|
using the methods CDC::Polygon and CDC::SetBkMode(TRANSPARENT)
but all I get is this :
,-------------------,
| |
| Blue |
| ,-------+---------,
| | |
'-----------+ Yellow |
|_________________|
Please give me a simple solution sticking with the MFC.
Thanks.
You cannot do this, regardless of whether SetBkMode is TRANSPARENT or OPAQUE since Polygon uses the currently selected brush to fill the polygon's interior. Instead what you should do is this:
Paint one rectangle first, paint the other rectangle next and then calculate the intersection of the two rectangles using CRect::IntersectRect (see http://msdn.microsoft.com/en-us/library/262w7389(v=vs.100).aspx).
If the intersection is non-empty, calculate the resulting "color blend" and create the appropriate brush and, using it, draw a third rectangle using.
For more information on how to blend the colors, check out Algorithm for Additive Color Mixing for RGB Values right here on StackOverflow.
I publish an OG action/object but the attachment layout of the action (which has been set to "Item") is simply ignored. On my timeline, I click on the date/time link to see the action in full details (along with the attachment)... but all I see is a box with object image in the center and the object title at the bottom:
------------------
| |
| |
| Image |
| |
| |
------------------
| Object Title |
------------------
Instead I expect to see a smaller image at the left side along with the title and other captions on the right side (like what "Item" layout preview is showing):
-----------------------------------------
| | Object Title |
| | Caption 1 |
| Image | Caption 2 |
| | Caption 3 |
| | Caption 4 |
-----------------------------------------
And the OG tags of my object page, hosted on my website, are correct (at least the Facebook OG Debugger says so!).
Does anyone know what I'm missing here?
Thank you,
