I am looking for a specific custom control. I am drawing some rectangles to my picture box, now I would like to display a tooltip when someone moves his mouse to one of the rectangles, so a hover rectangle-hover event. Does this sound doable at all? If yes, is there anyone that has made such a control already? If no, how would I go about making my own? Thanks!
Have a look at this. You can do some really cool things with this free tooltip library:

You can also try the ToolTip Class in Windows Forms.

I am newer to coding but, usually, when I have a question it is answered by a quick google search or video explaining my issue. The title is basically the question but I will elaborate: How do you round out the corners of a rectangular button in .axml? I have tried making a drawable folder with specific corner parameters set and applying that to the button background but it doesn't change the button in any way. I know that in .xaml you can simply use the CornerRadius tag but that isn't defined in .axml. Sorry if I am not being specific enough with my issue, like I said, I am new, but would be willing to elaborate further if need be.
Thank you all:)
I'm using wxWidgets 2.8 on a Linux box.
I'd like to get notifications of scroll events from wxListCtrl (or wxListView). Basically I want to be notified when someone uses the scrollbars.
I tried with EVT_SCROLLWIN and EVT_SCROLL without success.
Can someone provide me some sample code?
Unfortunately I cannot find any documentation/sample about this topic. Any pointer?
I need to intercept this event because I'm using a wxListView under MOTIF (sic) and when I scroll the list, the new items are not redrawn (basically I see the list empty until I click an item). So, my hack would be to call wxWindow::Redraw() after a scroll.
Any alternative solution to my original problem?
Thanks.
You won't get scroll events for what can be (even if it is not in wxGTK, actually) a native control, this is just not something that wxWidgets guarantees because it is very difficult (and maybe impossible) to implement in general.
Sorry.
Wondering if someone could help me....
I have a small .NET application where I have an Edit button on a main form. When the user clicks the Edit button, I want to popup a small form right next to it (on top of the main form) with a speech balloon tail attached on the side of the form pointing to the Edit button. So it gives the effect of a floating form pushed out from the Edit button.
I don't want the appearance of a normal speech bubble, I want it to look like an actual borderless form (with square corners). It could be a custom control or anything (however, I am not yet familiar with creating my own custom controls), but I need to add Text Controls, Pictures, Label Controls, etc. to this floating form.
Any help would be appreciated.
Thanks
UPDATE
I am trying to create something to this affect:
So imagine the ? being the Edit button and the other being a form with custom controls.
Like this?
To get this behavior:
Select an image which will represent your speech bubble. Put a PictureBox on the form, make it use this image. Place two labels, as above, adjust the font.
Pick your transparency key (color). Your image background and form background need to be set to that. I used black for demo purposes, which is a bad choice if you plan to have any black or text in your speech bubble. Set form's TransparencyKey property to this color in designer. More about TransparencyKey on MSDN.
(final step, not shown on the screenshot). Set FormBorderStyle = None.
Also make sure you have other ways to close your bubble, because X will be unavailable.
The final result may look something like the following:
Note: You may notice some drawing artifacts, most images on the internet have smooth borders, and transparency key does not support shades, has to be exact color. If you are fine with these minor artifacts, feel free to leave it at that. Or, edit it to get rough borders. Or find another one that better suits your needs.
In VB6 I have been using pictureboxes as containers a lot.
For example I put 5 pictureboxes onto a form, and as soon as the user clicked the "Next" button, I brought the next picturebox into the foreground.
This has been extremely convenient.
Now I am fighting with doing something similar in VB.NET.
My attempts were not really successful. A picturebox does not really hold my controls, they seem to jump out now and then, and I can not really make out on which picturebox a control is currently located since the picturebox is not opaque as in VB6.
Can somebody please tell me how to do this in a good way in VB.NET?
This sounds like a job for the Panel control
For your issues with panels that you posted a screenshot for. Your panel is within another container, that's why it's displaying strangely. Try clicking the panel and cutting it (ctrl-x) then clicking the form header, and pasting it (ctrl-p). That will ensure it isn't within another control as sometimes that can happen in a way that isn't exactly obvious (like how you can see the control borders in your screenshot).
i am using vb.net
i just wanna ask if we can place a picture in a picture box in different places...
for example, we place a picture in the center of a picture box then we place another picture on the left side of the picture box. is it possible??
and also can we use one picture box that can contain more pictures or images on it???
to make it clear, it is a drag and drop senario, first you have to drag a picture from a toolbar for example, then you are to drop it on the picutre box, the problem is, we have to drop more than one picture in the picturebox, so is it really possible?
To my knowledge, this is not possible with the standard .NET picturebox control.
You could, however, create a custom control that would encompass this functionality.
I'm thinking it wouldn't be too complicated to do.
But probably the best way to handle it would be to create your picture box controls programmatically.
EDIT: Found something that might be useful for you, on CodeProject. Its a extended picturebox control, that seems to have multiple pictures in it.
Extended Picturebox
You will need to build all this functionality from scratch no matter which control you're using. You can use Picturebox, Button, Panel and so on, and they'll all provide the same fundemental for building the required functionality. I would suggest that you used a panel/canvas though. And as Jon suggested, subclassing a panel to create a custom control would properably be the best idea.
Inside this custom control, you will need to keep track of which images that have been dragged into the control, which images is affected by several mouse actions such as click, hover and release, and you will need to draw the pictures manually.
