Socoder -> Blitz -> File/Folder browsing in Blitz3D...
Wed, 19 Mar 2008, 12:54
Forklift_Fred	I'm sure I saw it here somewhere but I can't find it now... I'm looking for a quick solution for some basic file accessing. I've just about got by with what I've needed to do by placing my exe into the right folder and running it (it does various checks and stuff on whatever files are in the current folder) but I'd like to be able to run the program from a shortcut and navigate my way to the relevant folder from with it so I can also have a config/preferences file. As I say, I'm sure someone posted a snippet of functions for a basic file browser... unless it was at BB.com (I don't go there very often) So can anyone help? (either point me to it or give me some direction on doing it myself) Thanks -=-=- Come rain or shine...

Afr0	but I'd like to be able to run the program from a shortcut and navigate my way to the relevant folder from with it so I can also have a config/preferences file. Not sure what you mean by this, really, but it sounds like you're looking at making your own registry entries with an install program. To read these from within Blitz, look at some dcls files that were written for use with various Windows libraries within Blitz. I'm sure I've seen some over at BlitzBasic.com -=-=- Afr0 Games Project Dollhouse on Github - Please fork!

Forklift_Fred	@ Afro: Thanks but that's a step further than I was wanting to go. Your right though, I think I confused things with my wording there! @ Phoenix: Thank you, that will certainly do the job. I can tweak it and mold it from there. Bit confused by the "." and ".." directories though, I thought "." was the root and ".." was the previous (up 1 level), they both appear to do the same here. Doesn't really matter though, I can easily add a root link and probably keep the two at the top for easy access. Really appreciate that. Thanks. -=-=- Come rain or shine...

Phoenix	Actually, they behave the same because I programmed them to do so. Couldn't be bothered giving the different behaviors Update the folder checking code to this: If(f\name$ = ".") ; Should strip everything except the two first letters (the drive name and a colon, eg C:) path$ = Left(path, 2) Else If(f\name$ = "..") ; We strip away the top directory from the path if we want to move up stripLoc = Instr(path, "\"+lastDir) path$ = Left(path, stripLoc) Else ; If we browse deeper into the system we just append the folder name to the path path$ = path$ + "\" + f\name$ EndIf --v

Forklift_Fred	Aaah fair enough Thanks for the update. I've modified the scrolling to stop it going beyond the top and bottom. It's a bit patchy at the bottom (and looks messy anyway!) but it does the job. Had to globalise n (which should probably be renamed now it's global) and added "Global static" and reset it with "static=MouseZ()" after the "scrollOffset = 0" in the folder checking. Then replace the "scrollOffset = MouseZ()20" with scrollOffset = -(static-MouseZ())20 If scrollOffset>0 Then scrollOffset=0 static=MouseZ() End If If -scrollOffset>((n20)-(GraphicsHeight()/20))/2 Then scrollOffset=-(Floor((((n20)-(GraphicsHeight()/20))/2)/20)*20) static=static-(MouseZSpeed()+1) End If --v Like I said, it's messy! Next step is to add the keyboard function of Home to scroll to the top and maybe Page Up/Down because I like to use the keyboard sometimes -=-=- Come rain or shine...

Forklift_Fred	OK, something wasn't right and like I said, it was "a bit patchy at the bottom" and now I know why. Where you had it scrolling at a rate of *MouseZ()20** I took that to be the line spacing (although I usually use 15 myself and it clearly states in your comments that you used 14!!) thus all the messy calculations 20 and /20 were wrong. When I added Home* and End control it became all to apparent when the Windows folder listing wasn't even going half way! So I eventually resolved that and added cursor control and struggled with setting the static value correctly... The easiest way was to change the fixed relationship between MouseZ() and scrollOffset into a relative increment relationship with MouseZSpeed() so it worked the same as the keyboard. Thus I have come to a much cleaner code and removed the static variable I now have the following globals set up... Global n Global maxoffset Global linesperpage Global lineheight=StringHeight("test") --v Where lineheight is variable depending on the size of the font used (and has to be set before the directories are read to prevent a divide by zero error!) and maxoffset stops the bottom of the list from scrolling too high up the screen. These are all set at the end of the GetDirInfo() function thus: lineheight=StringHeight("test") linesperpage = GraphicsHeight() / lineheight maxoffset = (n - linesperpage + 2) * lineheight If maxoffset < linesperpage Then maxoffset = 0 --v Now replace the scrolling section of the code (originaly just *scrollOffset = MouseZ()20 at the top of the While** loop with this... mzs = MouseZSpeed() If KeyDown(208) Then ; Up scrollOffset = scrollOffset - 2 Else If KeyDown(200) Then ; Down scrollOffset = scrollOffset + 2 Else If KeyHit(201) Then ; Page Up scrollOffset = scrollOffset + linesperpage * lineheight Else If KeyHit(209) Then ; Page Down scrollOffset = scrollOffset - linesperpage * lineheight Else If mzs Then scrollOffset = scrollOffset + mzs * lineheight End If If scrollOffset > 0 Or KeyHit(199) Then scrollOffset = 0 End If If -scrollOffset > maxoffset Or KeyHit(207) Then scrollOffset = -maxoffset End If --v Note the addition of mzs = MouseZSpeed() to go along with the my, mx, mh1 abbreviations, this is what increments the scrolloffset. Putting it all together, you end up with...

Forklift_Fred	Actually, it wasn't that hard A couple of fiddly moments where the scrollbar insisted of scrolling up when the mouse was down but not moving - which I think was due to numbers being rounded off in the original code and then fall short when I converted it back. I've added a global variable for the width of the scrollbar so when the file checking code sets the positioning it now says itemX = scrollbarwidth + 5 but apart from that, replace the existing scrollbar code with this... ; Make Scrollbar Color 64,64,64 Rect 0,lineheight,scrollbarwidth,GraphicsHeight()-lineheight Color 128,128,128 barheight=((GraphicsHeight()-lineheight)/(1+(n/linesperpage))) barpos=((GraphicsHeight()-lineheight-barheight)(Abs(scrollOffset+1)))/(1+maxoffset) Rect 1,lineheight+1+barpos,scrollbarwidth-2,barheight Color 64,0,0 Rect 2,lineheight+2+barpos,scrollbarwidth-4,barheight-2 ; Add mouse control of scrollbar... If RectsOverlap(MouseX(),MouseY(),1,1,1,lineheight+1+barpos,scrollbarwidth,barheight) And maxoffset>0 Then If MouseDown(1) Then barpos=barpos+MouseYSpeed() scrollOffset=-barpos(1+maxoffset)/(GraphicsHeight()-lineheight-barheight)-2 ; Now lighten the bar color to show it is active Color 128,0,0 Rect 2,lineheight+2+barpos,scrollbarwidth-4,barheight-2 End If End If --v Sorted! \|EDIT\| had to add And maxoffset>0 to the If RectsOverlap... because if there isn't enough files to scroll then it would try to divide 0 and crash. -=-=- Come rain or shine...

Phoenix	You know, there is a GetKey() command
Sat, 22 Mar 2008, 18:05
Forklift_Fred	Yes but... does it make much difference? I avoided it thinking it was a 'wait until a key is pressed' command but that would be WaitKey()! I've just got into the habit of KeyHit() for using cursor keys. I suppose you'd be checking ASCII values rather than looking up in an array. Oh well, mine works well enough. Mind you, Backspace, Home, End, PageUp and PageDown would still need to be KeyHit() -=-=- Come rain or shine...

Forklift_Fred	One last update (I think...) I thought I'd already put this to bed but after adding a load of my other code into it for its ultimate purpose and got that all working right, I was running a few tests and found that the scrollbar wasn't actually working correctly. It was OK for small listings where the bar doesn't move very much but longer file lists and therefore a smaller bar, lead to it jumping a lot further out of place. I went back in and after playing with the maths, resorted back to my original idea of adding a flag to indicate whether it is being dragged or not and basically attaching it to the pointer. I didn't try it originally because I thought it would be more work... turned out to be much easier and spot on! I've not added the variables as Global or Local (I have never bothered with Local anyway!) as they are only needed when you first grab the scrollbar and get switched on then, otherwise the initial False and 0 are perfect... ; Make Scrollbar scrollerheight = gfxh - lineheight - 1 barheight = (scrollerheight / (1 + (n / (linesperpage + 1)))) barpos = ((scrollerheight - barheight) * (Abs(scrollOffset + 1))) / (1 + maxoffset) Color 64, 64, 64 Rect 0, lineheight + 1, scrollbarwidth, scrollerheight Color 128, 128, 128 Rect 1, lineheight + 2 + barpos, scrollbarwidth - 2, barheight Color 64 + ( grab * 64), 0, 0 ; ( grab * 64 ) lightens the bar color if it is being dragged Rect 2, lineheight + 3 + barpos, scrollbarwidth - 4, barheight - 2 ; Add mouse control of scrollbar... If RectsOverlap(MouseX(), MouseY(), 1, 1, 1, lineheight + 2 + barpos, scrollbarwidth, barheight) And maxoffset > 0 Then If MouseDown(1) Then If Not grab Then grab = True mousegrab = MouseY() - barpos End If barpos = MouseY() - mousegrab scrollOffset = -barpos * (1 + maxoffset) / (scrollerheight - barheight) - 2 Else grab = False mousegrab = 0 End If Else If RectsOverlap(MouseX(), MouseY(), 1, 1, 0, lineheight + 1, scrollbarwidth, scrollerheight) And maxoffset > 0 Then If MouseY() < barpos And mh1 > 0 Then scrollOffset = scrollOffset + (linesperpage -1) * lineheight If MouseY() > (barpos + barheight) And mh1 > 0 Then scrollOffset= scrollOffset - (linesperpage-1) * lineheight Else grab = False mousegrab = 0 End If --v You'll see it's grab and mousegrab that I've added (I've also abbreviated the GraphicsHeight() down to gfxh (defined at the start of the program, not here) and abbreviated the size of the overall scroller down to scrollerheight) I also made the scrollbar colour definition more dynamic rather than drawing it twice if it's being dragged. Oh and while I was there, I added the ability to click above or below the bar to scroll whole pages. I'm sure the whole thing can be repeated horizontally without much effort too if needed -=-=- Come rain or shine...
