QUESTION
I recently making a stoplight program (gui) and i can't figure it out which is wrong I dont know how to include the QTimer or any function for delay to make the color change and i tried the show function ended up getting two programs i really don't know how to fix my code yet can you please help me?
...ANSWER
Answered 2019-Mar-10 at 16:06This would be a hint in accomplishing it. You need to define some functions or objects to handle the different locations of the cycles. Furthermore use the function self.update()
to call the paintEvent
and application.processEvents()
to make the changes visible in the gui. You can use the code in the execution part and generate a more sophisticated function out of it.
EDIT: Try this approach with a dictionary, as it contains less code.
QUESTION
Im using PyQt5 and I know you can make other things like buttons move to other positions with move() but that isn't working for me in this instance, however it is working when I set up the positions for some of the buttons I made earlier.
For some reason when I try to make my widget DrawImage go to a certain part of the window It never does and instead just stays in the top left corner.
This DrawImage is going to be inserted into another class I have that sets up the window DrawImage will be placed in. Any ideas on how I can make this work?

has a preset layout as shown below:
this layout is used to set the toolbar
, menubar
, statusbar
, dockwidget
s and the centralwidget
. The layouts handle the position and the size of the widgets, that is why this error is generated. The solution is to set another widget as a central widget, and your DrawImage
is the son of this new widget.
QUESTION
Is possible insert element inside input fields? Here is an example.
What I can use to make that happen?
I was wondering about tables, It is possible make a table inside input field?
...ANSWER
Answered 2018-Apr-20 at 04:18No, you cannot have any element contained within an element.
It is an empty (void) element, and the closing tag must be ommitted.
Thus you cannot have any element contained within it.
QUESTION
I am new to python3 pyqt GUI development. I am trying to make a simple GUI which has various widgets spaced nicely in a compound layout structure of a QVBoxLayout which contains many QHBoxLayouts. When building the layouts, I use the addStretch() method to space out the widgets but the circles which are painted do not show up in the GUI display. However if I comment out all of the addStretch() function calls then the GUI displays all the desired widgets (however the spacing is not good looking). Where are the circles going?
Please help!
Code where circle widgets do not show up.
...ANSWER
Answered 2018-Feb-03 at 03:53When you use addStrech()
the layouts will use sizeHint()
as the size, since the size is not set so it is not visible, the solution is to set that property. Another suggestion is that you do not make the QPainter
a member of the class since it consumes memory in an unavoidable way, just make it a local variable. Another recommendation is that you call update()
inside setColor()
method and it does not save you code lines and you have a cleaner code.
QUESTION
Im trying to find the components/head of a 3D vector with in java. I have a already got the x,y,z variables setup and the corresponding rotation variables. Using these variables and vector math, I want to find the components after they have been rotated. You can think the x,y,z variables as a vector being translated.
Using the math from this post: Rotating a Vector in 3D Space
I wrote some code that was supposed to calculate position based on that last post:
