I have a tab that is to display data that is to be prepared for a report. Kind of like a preview. What I want is to take a screenshot of graph generated in another tab.
Kind of similar to scanning an image. So the initial tab generates 3 graphs under each other that fit in the screen. I basically want the screen shots of the graphs to post them along with the data in the second tab.
The second image is where I want the content of the first image to be posted. How do I go on about that?
I worked on some design on inkscape and something weird happened. I can no longer see the contents for file when i open inkscape. All I see I blank whitespace, I don't even see the black rectangular borders I used to see before. When I look at the svg file in finder I can see the contents in the file thumbnail but once i open in inkscape I dont see anything. I tried fitting the page to the content and changing width and height of the document and nothing happened.
I am new to inkscape so this is confusing to me. Anybody have any ideas how to rectify this?
Open your document in Inkscape then press 5 to zoom to the page (or using the menu: View → Zoom → Zoom Page).
You should see the drawing:
I need to add a title bar named "Crop Image" in this Cocoapod.
Please help me
I'm the developer of TOCropViewController. :)
There's no feature in the library at the moment to display text above the cropping content right now. But it would be fairly trivial to add a UILabel to the view and position it near the top of the view.
The challenge is that you'd then need to account for it when the device is rotated sideways. At the moment, the cropping content will fill the entire height of a horizontal device, so you'd need to override that to account for the text.
It's been a while since I wrote it, but I did include a property in the vertical layout code to add padding to the top of the view controller, so it SHOULD be relatively easy.
I sadly don't have time to add it myself, but I made an issue on the repo and added the pr requested tag. Hopefully someone with more free time than I do can add it. :)
I have small application in famo.us framework. There are 5 images. I want drag images. requirement is like when i drag firstImage, second image should be visible behind the first image. i tried to show second image on dragging up of firstImage, but it hides firstimage.
so is it possible to show second image behind the first image ??
Thanks
Check the z position of your images. Chances are you're encountering z-fighting, where two elements exist on the same position on the same z-axis. Try changing the z-index of the images to different values first to see if that fixes it.
Otherwise, check the 3d-transform you've supplied to famous to make sure your images aren't resting on the same z-value.
I'm trying to implement some drag and drop functionality for a material system being developed at my work. Part of this system includes a 'Material Library' which acts as a repository, divided into groups, of saved materials on the user's hard drive.
As part of some UI polish, I was hoping to implement a 'highlight' type feature. When dragging and dropping, windows that you can legally drop a material onto will very subtly change color to improve feedback to the user that this is a valid action.
I am changing the bar with 'Basic Materials' (Just a CWnd with a CStatic) from having a medium gray background when unhighlighed to a blue background when hovered over. It all works well, the OnDragEnter and OnDragExit messages seem robust and set a flag indicating the highlight status. Then in OnCtrlColor I do this:
if (!m_bHighlighted) {
pDC->FillSolidRect(0, 0, m_SizeX, kGroupHeaderHeight, kBackgroundColour);
}
else {
pDC->FillSolidRect(0, 0, m_SizeX, kGroupHeaderHeight, kHighlightedBackgroundColour);
}
However, as you can see in the screenshot, the painting 'glitches' below the dragged object, leaving the original gray in place. It looks really ugly and basically spoils the whole effect.
Is there any way I can get around this?
Remote debugging is a godsend for debugging visual issues. It's a pain to set up, but having a VM ready for remote debugging will pay off for sure.
What I like to do is set a ton of breakpoints in my paint handling, as well as in the framework paint code itself. This allows you to effectively "freeze frame" the painting without borking it up by flipping into devenv. This way you can get the true picture of who's painting in what order, and where you've got the chance to break in a fill that rect the way you need to.
It almost looks like the CStatic doesn't know that it needs to repaint itself, so the background color of the draggable object is left behind. Maybe try to invalidate the CStatic, and see if that helps at all?
Thanks for the answers guys, ajryan, you seem to always come up with help for my questions so extra thanks.
Thankfully this time the answer was fairly straightforward....
ImageList_DragShowNolock(FALSE);
m_pDragDropTargetWnd->SendMessage(WM_USER_DRAG_DROP_OBJECT_DRAG_ENTER, (WPARAM)pDragDropObject, (LPARAM)(&dragDropPoint));
ImageList_DragShowNolock(TRUE);
This turns off the drawing of the dragged image, then sends a message to the window being entered to repaint in a highlighted state, then finally redraws the drag image over the top. Seems to have done the trick.
