GUI creation in python using tkinter part 1

Overview

When executing a tool made with python, there is no problem if you call it from the command line if you made it yourself, but if it is a tool used by people who are not related to development, it is better to be able to operate it from the screen It's convenient. I researched various things to see if I could make an application with python and summarized the contents I made. It's still not very well made, so I plan to adjust it gradually.

Things necessary

• python 3.7.2
• pandas
• numpy

Publication place

It is published on github. https://github.com/snowpff14/etcresource/tree/master/pythonGui

Processing content

Script for operating selenium practice site see here, script for adding columns and deleting rows in Excel file [see here](https: // qiita.com/snowp/items/94f8bb06a08e42af6bba) can now be started.

• When using a variable text area (including button display name and label) on the screen, use StringVar () as shown below.

    inputFolder=StringVar()
    outputFolder=StringVar()

• The following opens the file dialog and stores the selected file path in the text box.

    def openFile(self):
        fTyp = [('','*.xlsx')]
        iDir = os.path.abspath(os.path.dirname(__file__))
        filename = filedialog.askopenfilename(filetypes = fTyp,initialdir = iDir)
        return filename

    def fileButton(self):
       filename= self.openFile()
       self.inputFileName.set(filename)

• The following is where the actual processing works. I use thread because the screen freezes until the processing is finished. The button is defined as doExecute.

    def doExecute(self):
        # threading.Lock
        thread=threading.Thread(target=self.execute)
        thread.start()

    def execute(self):

        excelFile=pd.ExcelFile(self.inputFileName.get())
        reserveSheetTemp=excelFile.parse(sheet_name='Reservation sheet',dtype='str',header=1)
        print(reserveSheetTemp.head())
        log=LoggerObj()
        driver=webdriver.Chrome('C:/webdrivers/chromedriver.exe')
        driver.get('http://example.selenium.jp/reserveApp/')

        reserveSheet=reserveSheetTemp.query('Invalid flag!= "1"')
        testSideOrder=TestSiteOrder(driver,log,'test')
        #Enter working hours
        testSideOrder.inputOrder(reserveSheet)

        testSideOrder.createOkDialog('Processing completed','登録Processing completed')

• Create a screen definition using tkinter.TK () as shown below.
• Set the window title with title
• Define the screen size etc. with Frame.

root= tkinter.Tk()

    def main(self):
        root.title("Python GUI")
        content = ttk.Frame(root)
        frame = ttk.Frame(content,  relief="sunken", width=400, height=500)

• Use grid to place labels, buttons, and other parts on the screen as shown below. (Partially excerpted)
• By using grid, it is possible to adjust the vertical and horizontal positions.
• Variable items can be reflected by specifying the items declared in StringVar using text variable.
• Set the function to be started by command.
• Finally, you can keep the screen displayed by calling mainloop ().

        content.grid(column=0, row=0)

        title.grid(column=0, row=0, columnspan=4)

        fileLabel=ttk.Label(content,text="Reservation information")
        resultFolderLabel=ttk.Label(content,text="Folder specification")

        fileInput=ttk.Entry(content,textvariable=self.inputFileName,width=70)
        resultFolderInput=ttk.Entry(content,textvariable=self.outputFolder,width=70)

        self.progressMsgBox=ttk.Label(content,textvariable=self.progressMsg,width=70)

        self.progressBar=ttk.Progressbar(content,orient=HORIZONTAL,length=140,mode='indeterminate')
        self.progressBar.configure(maximum=10,value=0)

        fileInputButton=ttk.Button(content, text=BUTTON_LABEL_REFERENCE,command=self.fileButton)
        resultDirectoryInputButton=ttk.Button(content, text=BUTTON_LABEL_REFERENCE,command=self.inputResultFolderButton)
         
        executeButton=ttk.Button(content,text='Run',command=self.doExecute)
        fileExecuteButton1=ttk.Button(content,text='File operation Insert execution',command=self.fileInsert)
        fileExecuteButton2=ttk.Button(content,text='File operation delete execution',command=self.fileDelete)
        root.mainloop()

When you start it, the following screen will be displayed.

For the time being, this time around Continued created
