python - Pyqt4: Use of Marker Numbers in Qscintilla -

-

i want know why marker number used , how 1 31 marker numbers different each other. , how add custom marker symbol gradient,pix map or image etc example these blue glittery dots in given image.:-
margin design pyqt4

marker defined in following code:-

 circle_marker_num = 0 ...... def __init__(self, parent=none):    super(simplepythoneditor, self).__init__(parent)    self.markerdefine(qsciscintilla.circle,self.circle_marker_num)    self.setmarkerbackgroundcolor(qcolor(66, 66, 255),self.circle_marker_num)    ......  def on_margin_clicked(self, nmargin, nline, modifiers):     # toggle marker line margin clicked on     if self.markersatline(nline) != 0:         self.markerdelete(nline, self.circle_marker_num)     else:         self.markeradd(nline, self.circle_marker_num)

the answer question "why marker number used" simply: why not? sort of identifier has used, , number seems reasonable choice.

the markers have pre-defined meaning numbers 25 31, used fold-margin symbols. numbers 0-24 have no pre-defined meaning, can use them in way like. , in fact, if don't use folding, can use 32 markers in way like.

you can define pixmap, image, or text character symbol use marker. like:

    pixmap = qtgui.qpixmap('image.png')     self.markerdefine(pixmap, self.circle_marker_num)

and other variants work in similar fashion.

ps:

you have answered points (and more) in question consulting excellent documentation available:

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.
