Button bitmap with 2.6.0 Topic is solved

[MatthewDP]

Hi all,

wxWidgets 2.6.0, MSW XP SP2

I updated from 2.4.2 to 2.6.0 and I ran into a problem.
When adding bitmap pictures to my toolbar buttons, the bitmaps appear to be inverted in color. [I'm not sure it's exactly a color inversion, but the normal gray background is now green, and all the colors are different.]

Additionally, a button that is set as disabled is now completely grayed-out -- the image is just a blank gray square instead of the normal "unenabled" looking picture that was there before.

I have included the code below. Any idea how to fix the problem?

Thanks for your help,
Matt.

Code: Select all

	wxBitmap newBmp;
	if(!newBmp.LoadFile((m_configs.getAppDirectoryPath().string() + "/Img/ButtonNew.bmp").c_str(), wxBITMAP_TYPE_BMP))
		newBmp.Create(15,15);

	wxBitmap openBmp;
	if(!openBmp.LoadFile((m_configs.getAppDirectoryPath().string() + "/Img/ButtonOpen.bmp").c_str(), wxBITMAP_TYPE_BMP))
		openBmp.Create(15,15);

	wxBitmap saveBmp;
	if(!saveBmp.LoadFile((m_configs.getAppDirectoryPath().string() + "/Img/ButtonSave.bmp").c_str(), wxBITMAP_TYPE_BMP))
		saveBmp.Create(15,15);

   const int ID_TOOLBAR = 500;
   long style(0);
   style &= ~(wxTB_NOICONS);
   style |= wxTB_FLAT | wxTB_TEXT | wxTB_HORIZONTAL;

	//Create and fill the tool bar
        wxToolBar* toolBar = this->CreateToolBar(style, ID_TOOLBAR);

	int toolID = IDtb_New;
	toolBar->AddTool(IDtb_New, "New", newBmp);
	toolBar->AddTool(IDtb_Open, "Open", openBmp);
	toolBar->AddTool(IDtb_Save, "Save", saveBmp);

   //Realize the toolbar
   toolBar->Realize();

Try converting the images to png, it will save space too, and also your problem may be solved. I think its the palette problem, set the palette of the dc by the bitmap pallete.

Code: Select all

newBmp.Create(15,15);

Any body have a idea, what this is doing after loading the image, it that necessary. I haven't used it.

I suppose MatthewDP want to do something like: load the bitmap from the disk or (if cannot load) create at least an empty bitmap.

Re: creating a blank bitmap if the other is not loaded, that was exactly my intention. If I couldn't load the bitmap, I wanted some way to continue to run the application. This just guarantees that a bitmap is available.

Perhaps I could do something else, but that's a quick solution for now.

I re-saved the bitmaps as 24-bit bitmap images (from MS Paint). This solved the problem. I'm not sure what exact format they were before (16 or 256). But 24 bit seems to work.

Thanks,
Matt.
