Hey guys. I have a quick question. How do I get the image generated by a JComponent.paint or paintComponent? I have a JComponent which I use as a 'workspace' and where I have overwritten the paintComponent method to my own. The thing is that my workspace JComponent also has children which has their own paintComponent methods. So when ...
I have subclassed java.awt.Frame and have overridden the paint() method as I wish to draw the entire contents of the window manually. However, on the graphics object, (0,0) corresponds to the upper left hand corner of the window inside the title bar decoration, not the first drawable pixel. Can I determine the co-ordinate of the first ...

I'm writing my Delphi TGraphicControl paint procedure. I create a canvas and I stretchdraw it onto the graphic area. It works well. Then I repeat this with another Stretchdraw onto the graphic area but it is drawn in the area of the first Stretchdraw and not onto the graphic area as I direct it. Is there a way that can place both stre...

I have to use a PictureBox, and using the System.Drawing.Graphics class' drawing primitives to draw the chart.

For data entry, I'm using a DateTimePicker control that sits on top of the WebBrowser control, which I have programmed to move on top of the cell of the table in the WebBrowser control when the WebBrowser control is clicked on. (If you want to ask ...
As I see it, there are two ways to handle mouse events to draw a picture. The first is to detect when the mouse moves and draw a line to where the mouse is, shown here. However, the problem with this is that with a large brush size, many gaps appear between each "line" that is not straight since it is using the line's stroke size to c...
I am trying to experiment with expanding paint-like program adding custom features to it. Can you suggest a simple open source paint-like program written in C and using GTK+ library which I could expand? It should compile in Linux but also in Windows (using MinGW). Thanks.

I've got a couple of really old MSDos based paint programs. They work on palette indexed image buffers. They have a number of spectacular shape drawing tools, brushes and effects that simply do not exist in any modern paint program- Particularly not whilst staying within the "bounds" of a low color palette indexed image. I would like to ...

I have a DataGridView with both horizontal and vertical scrollbars. When running the application within Visual C# using "Start debugging" everything looks fine, but when running the application itself after building it the vertical scrollbar doesn't paint correctly (it's not really visible but there is space taken up as if it should be...
Hi, I'm working on a Swing application (currently running on Java 1.6 update 11) which has some intermittent paint refresh problems (e.g. there are artifacts etc.). This only happens to some users of our application but not others. After doing some research, I found that setting the property sun.java2d.d3d to false may help and in fact...
I'm developing a fair sized hospital simulation game in java. Right now, my pain method is starting to look a little big, and I need a way to split it up into different sections... I have an idea, but I'm not sure if this is the best way. It starts by painting the grass, then the hospital building, then any buildings, then people, then a...

The problem is that when I call the move function it loops until the image is where the user clicks but it wont repaint until I break out of the loop even though the thread doing the moving and the...
Hi girls and guys! I'm currently in the planning phase for a project of mine. I thought about using the MVVM-pattern for my application for testability, maintainability etc. I have only started to get my head around MVVM but there is one thing that I just can't figure out in the context of my planned application. My application aims t...
