I try to set an Image for TabBarItem, but the Image always appear with the original size even though I resizable with other size

I can't see anything about resizing in the docs, although they have an example of "maximum cropped dimensions".
Any idea how to do that?
Yes, you can.
When getting the cropped canvas, you can specify your desired size and then send to server or do whatever
getCroppedCanvas is the method you may want to use with specifying width & height of your resize
I want to increase the size of my tooltip as i want to insert an image as background to my tooltip. I am able to apply an image to my tooltip but the problem is the size of the tooltip being small only the upper part of the image is being displayed.
I am displaying image using Graphics Draw Image function. And I want the tooltip to take original size of an image without creating a rectangle as I tried all already.
I don't want to create my own tooltip. Just increase size of existing one.
I resolved it!! Just needed to add spaces on the property Tool tip on mytooltip on that control on which tool tip is used.Here i have used tool tip on my buttons.
I'm trying to retrieve file icons on Windows. I follow this guide http://pogopixels.com/blog/getting-the-48x48-or-256x256-icon-of-a-file-on-windows/
I use SHIL_JUMBO to get the maximum size possible. However, not all icons returned are big enough, such as the QuickTime icon in the attached image. The size of the whole pixmap returned is still 256x256 but it does not fill the entire space. My program will then scale it down, making it too tiny to see.
I'm wondering if I can retrieve some extra info such as the size of the original icon, so I know that it's too small to scale down.
In a MFC SDI application containing a single CView, I pass the output device context pDC->m_hDC to a mapping library to render the map within the CMyView::OnDraw() method.
I would like the rendered image to appear in the centre of the cview surrounded by a black background, i.e. the image size would be smaller than the CView client rect size. I have experimented with CDC::SetViewportOrg() and set the device size in the mapping library, however unfortunately the mapping library draws outside of the device size set.
What is the best way of limiting the image to the desired size? Should I be looking at clipping functions? Or do I have to manually draw over the undesired parts of the image.
Well you can do it 2 ways.
1) You could SetBoundsRect to the boundaries you want.
2) You could just bit blt the section of the image you want into the DC.
Method 2 would be my preferred method as there is no extra logic. It only ever even tries to draw the part you are blitting :)
We have a touch screen, and the toolbar is too small to hit with my meaty fingers. Is there an easy way I can have an option to make the toolbar buttons bigger and easier to hit?
So far I've attempted a few things:
m_toolbar.SetSizes( CSize(64,64), CSize(50,50) );
m_toolbar.SetSizes( CSize(64,64), CSize(50,50) );
m_toolbar.GetToolBarCtrl().SetButtonWidth( 64, 64 );
m_toolbar.GetToolBarCtrl().SetButtonSize( CSize(64, 64) );
None of these approaches stretches the images as well. The buttons get larger, and are fully functional, but the images do not overlap the buttons the way they normally would. I would prefer to keep a single image list for the icons, and have the images stretched to fit.
At toolbar creation time, create an empty CImageList with size 64x64 (let's call it large). Load the original image list from resources (we call it small).
Iterate over each image in small and copy/resize it to large.
Then assign large to your toolbar. Somewhat cumbersome bui should work.
HTH,
As far as I know there is no way to make images resize with the size of the buttons. MFC applications use bmp and not vectorial images.
So you will have to supply a bmp images with the disired sizes.
You can use a CImageList and SetImageList to set the images but then you will have to
initialize images there with the disired size also.
