Hello, I'm using a wxAuiManager with a pane that can float and can be docked. When it is docked on the whole height of its parent, it is OK since its height is available to correctly manage the scroll bar of the panel embedded in the pane: toolbar1.png But I remarked that it can also be docked at an...

Thanks for the explanation doublemax.

Just to confirm that as Kvaz1r stated, the solution with Bind works well.
Of course, two methods are necessary to catch both
wxCommandEvent and wxMouseEvent.
Moral of the story: don't use event tables
Many thanks for the helps,

Pascal

Hello Kvaz1r,

Many thanks for your valuable help and piece of code.
I'm going to replace the macro with a call to Bind.
Then I 'll just have to adapt the code to manage my slider range.
Many thanks again for your time,

Pascal

I have double-ckecked and still have the same issue. To be more precise: I have several sliders, so I use the range macro (this could be the problem): EVT_COMMAND_RANGE(ID_SLIDER, ID_SLIDER + MAX_PARAM_COUNT, wxEVT_LEFT_DOWN, Effects::OnSlider) I've tried the 2 following OnSlider implementations: (1...

Hi all,

I'd like to detect a left mouse click on a wxSlider thumb (hence the slider value is not changed).
But there is no counterpart to wxEVT_SCROLL_THUMBRELEASE and mouse events are not available
for a wxSlider.
Any help will be welcome.

Regards,
Pascal

I kind of solved my issue. The fact is that my bitmap was not managing transparency (i.e. the alpha channel). So, I tried to initialize it from a PNG file (that manages transparency) and the code works great. I did it with: bitmap= wxXmlResource::Get()->LoadBitmap(wxT("bitmap_in_png_file")); Now I j...

Hello, I'm using a wxGraphicsContext to make some anti-aliased drawing in a bitmap. I want to draw a kind of donut with the hole and the outside transparent. All I can have is a donut with a black hole and a black outside. :-( Here is my code (obviously, using the transparent brush is not the thing ...

Wow! I missed that (but you didn't!).
Only 2 lines to change and it works great!
Doublemax, you're the best and saved my evening.
I am very grateful for your valuable help.
Have a very good weekend!

Thanks for your advice that offers a solution but that doesn't fully answer my expectation: Actually, until now I'm used to call wxMessageBox like this: wxMessageBox(_("bla bla")), i.e, with just one parameter and the message box is always well centered. I'd like to keep on doing the same with myMes...

Screen Shot 2018-07-20 at 19.17.49.png Thanks to you Doublemax, the implementation was quite straightforward. But I still have troubles with automatically centering the message box on the app frame: Calling myMessageBox (my function that replaces wxMessageBox) does not mention the parent window. On...

Great, I'll get right on it. Thanks!

I plan to make a skinned version of wxMessageBox. I wonder about some aspects:
- Should a class to do that be a good idea (since wxMessageBox is a function)?
- If so, which should be the best base class to derive?
- How to get the modal behavior?

Many thanks for any suggestion,

Pascal

Was your EVT_ERASE_BACKGROUND event handler completely empty (that's how it should be) ? Yes Do you use double buffering (wx[Auto]BufferedPaintDC) in the paint event handlers? There is still some noticeable (but different kind of) flicker when resizing the main frame. Not yet, but I will check it, ...

I have investigated and remarked that the flicker didn't happen in the class where the EVT_ERASE_BACKGROUND event was not bound. I also remarked that all my OnPaint methods started with the right dc.Clear() that ensures to erase with the right color. So I removed the EVT_ERASE_BACKGROUND binds and t...
