objective c - NSTextField dynimic height in NSTableView -

-

there nstextfield in nstableview.

the height of text in window resizing increased. not grow cells in table view.

in case, height of table view cell alter how like?

in short, when resizing size of text view, want change size of cell.

like this: (mac store) enter image description here

- (cgfloat)tableview:(nstableview *)tableview heightofrow:(nsinteger)row; {     kfcustomcellview *cellview = [tableview makeviewwithidentifier:@"maincell" owner:self];      nsstring *comment = [[_commentlist objectatindex:row]valueforkey:@"comment"];      [cellview.comment setstringvalue:comment];      float cellheight = [comment heightforstringdrawing:comment font:[cellview.comment font] width:self.view.frame.size.width * 0.8];      if (cellheight > cellview.comment.frame.size.height)     {         return (cellheight + 65);     }      return  90; }

use following approach resize cell height according textview content :

- (uitableviewcell *)tableview:(uitableview *)tableview cellforrowatindexpath:(nsindexpath *)indexpath  {     static nsstring *datacellid = @"datacell";     datacell = (cell *)[tableview dequeuereusablecellwithidentifier:datacellid];     if(!datacell)     {         datacell = [[[cell alloc] initwithstyle:uitableviewcellstyledefault reuseidentifier:datacellid] autorelease];     }      datacell.datacelltextview.tag = indexpath.row;     datacell.datacelltextview.text =[yourdataarry objectatindex:indexpath.row]; return datacell; }  - (cgfloat)tableview:(uitableview *)tableview heightforrowatindexpath:(nsindexpath *)indexpath {     #define paddingfortablerowheight 24      nsstring *text;     if([yourdataarry count] > indexpath.row)     {         text = [yourdataarry objectatindex:indexpath.row];     } else {         text = @"";     }       uifont *datafont = [uifont boldsystemfontofsize:16.0f];       cgsize textsize ;       if([uicommonutils checkifios7])         {         // ios7             textsize = [text boundingrectwithsize:cgsizemake("your cell width", maxfloat) options:nsstringdrawinguseslinefragmentorigin attributes:@{nsfontattributename:datafont} context:nil].size;         } else {             textsize = [text sizewithfont:datafont constrainedtosize:cgsizemake("your cell width" - paddingfortablerowheight,maxfloat)];         }        float textviewheight =  max(kdefaultcellheight, textsize.height+paddingfortablerowheight);    return textviewheight; }   -(void)textviewdidbeginediting:(uitextview *)textview {   [self scrolltocursorfortextview:textview]; }  -(void)textviewdidendediting:(uitextview *)textview {     if([yourdataarry count] > textview.tag)     {         [yourdataarry replaceobjectatindex:textview.tag withobject:textview.text];     } }  - (void)textviewdidchange:(uitextview *)textview {     dataupdated =yes;     if([yourdataarry count] > textview.tag)     {         [yourdataarry replaceobjectatindex:textview.tag withobject:textview.text];     }     [self performselector:@selector(datareload) withobject:nil afterdelay:0.0];     [self scrolltocursorfortextview:textview]; }  -(void)datareload {     [self.tbl beginupdates];     [self.tbl endupdates]; }

i used pyinstaller create standalone exe file pyqt project. did not use single file option because exe created single file option takes long open. therefore, pyinstaller created dist folder contains bunch of files including program.exe file. create setup.exe file place contents of dist folder in program directory , create shortcut in start menu , on desktop. want super simple user. maybe setup.exe files when download program cnet. found inno-setup, looks promising. however, not know if there special considerations because program standalone program create python/pyqt program. thanks! have experience task? there program using task not know about? inno-setup or nsis easiest use. tell them files include , put them , create nice installer you. wrote short tutorial on experiences using innosetup might find helpful: http://www.blog.pythonlibrary.org/2008/08/27/packaging-wxpymail-for-distribution/ note tutorial based around wxpython app wrote, concepts same.
