TRACKBAR

[polle12]

Hello!
Does anyone know how to change the size of the slider? I want to create a trackbar which reminds Windows volume setting (thin line & relatively big slider).

I assume you're using Win32. If so you can just use SetWindowPos() or MoveWindow() to set the size of the trackbar control.

Yes I'm using Win32, but the problem is that I don't want to change the size of the whole window. I just want to modify my trackbar by making the thumb bigger or the channel thinner. Like here (first example window):

Apart from drawing it yourself, it looks like you can only change the size of the slider by specifying TBS_FIXEDLENGTH when you create it and using TBM_SETTHUMBLENGTH to set the size of the slider.

Now I have a slider that looks good. With TBM_SETTHUMBLENGTH message one can change the size of the thumb, but in my case it didn't work, because I had specified TBS_ENABLESELRANGE. This style also makes the channel bigger and my problem was solved by removing it.

TBS_ENABLESELRANGE changes the size of the channel so that the user can see which part of the channel is selected. If you dont need the user to select a range then you dont want to use that style.
