I remark this line and re try run under win64, but still raise exception when use myForm.Show; I can not trace this exception, I added onShow event but not trigger. raise exception and terminate application. whats yours suggestion? TStatusBar bar has a bug ?? or what can be problem ? TStatusBar.Canvas.TextWidth() needs Canvas.Handle when you use it. Canvas.Handle isn't available until there's no paintevent on TQtWidget handle, so that may be problem. Try to use temporary bitmap for text measuring and see if it works. zeljko TPageControl except Error in win64 qt on show, no any error on create. TPageControl.Visible := False; I added this in form.oncreate event. This form now open without error, but no page control. pagecontrol has a TBCButton and thats have a just onclick event, they work like a menuitem for me. And usually my all forms is inherited from same main form. (I added lfm file's code). that create exception too. and just in win64. osx qtx64, win32 qt work normally. There is no except error. not test in linux yet.

[Lazarus] Disabled images
Hi All, I have a toolbar with buttons on it, that are linked to actions. I also note, that there is a property called DisabledImages. I'm presuming this is to do with images that will be displayed on the toolbar, instead of the normal images, when the action is disabled? If this is the case, how do I specify which image relates to the correct action in the ImageList? Hope that makes sense?

Re: [Lazarus] Disabled images
Your understanding that the disabled images will be used instead of the normal images if the action is disabled is correct. You may have noticed also there are also HotImages which become active if the mouse is moved over a toolbutton. BUT: Since there is only one ImageIndex all Imagelists (Images, DisabledImages, HotImages) must be in sync, i.e. same count and same order of images. This is some kind of restriction for practical use. Am 02.07.2015 um 14:00 schrieb Richard Mace: Hi All, I have a toolbar with buttons on it, that are linked to actions.
