08:21 <PulkoMandy> Mibi88, in the code about SrawString you shared earlier, you were trying to use this function: void DrawString(const char* string, const BPoint* locations, int32 locationCount);

08:22 <PulkoMandy> this one expects an array of BPoint, one for each character of the string, instead you want to use this one: void DrawString(const char* string, BPoint location, escapement_delta* delta = NULL); with a single point for the first character and then move the pen automatically for the next characters

08:22 <Mibi88> Oh, I didn't noticed it. Thanks!

08:23 <PulkoMandy> so that would be DrawString("Hello world", BPoint(10, 10)); for example (notice there is no "new" so it's not passed as a pointer in this case)

08:24 <Mibi88> > void DrawString(const char* string, BPoint location, escapement_delta* delta = NULL); : Yes that's what I was trying to use IIRC I got errors when not passing the last parameter. But now I got everything working already :D

17:17 <Mibi88> Hello, I'm trying to get the opened file from a filepanel on MessageRecieved. When saving files, from the example code, I get the saved file path with message->FindRef("directory", &ref) and message->FindString("name", &name), but I'm unable to do that on B_REFS_RECEIVED messages (nothing happens). How can I get the opened file? When looking at the doc it seemed correct, because a B_REFS_RECEIVED should be sent when the file is

17:17 <Mibi88> opened…

17:31 <augiedoggie> the B_REFS_RECEIVED_MESSAGE has "refs" fields in the message that you use instead

17:31 <augiedoggie> https://www.haiku-os.org/legacy-docs/bebook/BFilePanel_Overview.html#BFilePanel_Open_Notification

17:32 <augiedoggie> er, B_REFS_RECEIVED

17:34 <Mibi88> Thanks! I just found it out by reading a bit more.

18:23 <Mibi88> When I create a BScrollView with my hexView BView as following BScrollView* scrollView = new BScrollView("scrollview", hexView, B_FOLLOW_LEFT_TOP, 0, false, true);, nothing gets shown in the view when I add it to the layout, it's content stays blank. I searched in the haiku book and in the be book but found nothing…

18:25 <Mibi88> Ps: How do I let a widget in my BLayout fill the window? Currently it always takes up the half of it.

18:28 <Mibi88> I meant BLayoutBuilder

18:29 <augiedoggie> the view constructors without a resizing mode are generally used with the layout kit

18:31 <augiedoggie> there is a note at the top of the api page https://www.haiku-os.org/docs/api/classBScrollView.html

18:31 <augiedoggie> "Instantiates a new scroll view and connects it to the target view suitable for use in a BLayout"

18:33 <Mibi88> Oh ok, I mixed BLayoutBuilder and BLayout

18:34 <augiedoggie> LayoutBuilder is just a convenience wrapper to create a BLayout

18:36 <Mibi88> Ok, I got it working, I thought that I was using the other prototype. Thanks!

18:36 <augiedoggie> :)

18:37 <Mibi88> And for my size issue, I set the width to FLT_MAX when calling Add, but is there a more elegant solution?

18:39 <waddlesplash> you shouldn't need to set width

18:39 <augiedoggie> i'm not sure what FLT_MAX is

18:39 <waddlesplash> maximum value a floating point number can hold

18:39 <waddlesplash> but you shouldn't need to call Add with a value at all here if you're using layouts

18:39 <augiedoggie> yeah, but i mean, i thought the weights were 0 to 1

18:40 <augiedoggie> i must be thinking of a different api :P

18:42 <waddlesplash> ah, yeah. just 1 for a weight should work

18:53 <Mibi88> Thanks! I'm sorry to be asking so often, but I'm unable to set the expected size of my BView for the BScrollView to display scrollbars accordingly. I tried using SetExplicitPreferredSize (I also tried SetExplicitMinSize), but it messes up the whole layout: I can't shrink the window back down without having the scollbars offscreen…

18:53 <waddlesplash> there could are some oddities around BScrollView but I don't remember what they are off the top of my head

18:53 <waddlesplash> you could look at some existing application that does custom drawing with BScrollView

18:54 <waddlesplash> like DiskProbe, the hex viewer/editor

18:54 <waddlesplash> ... or does that just use scrollbars and not a full scrollview

18:54 <waddlesplash> I know the Contacts window definitely uses BScrollView at least

18:54 <Mibi88> Ok, I'll take a look at that.

19:00 <augiedoggie> maybe the child BView is being created with the old non-layout constructor

20:40 <mibi88[m]> I think that I found something helpful: https://github.com/HaikuArchives/BeSampleCode/blob/haiku/interface_kit/scrollbarapp/newsletter-article#L63, I just hope that it isn't too outdated 😂. I'll have to look at it tomorrow.
