    1. Save your files
    2. Close Qt Creator
    3. Delete the folder C:\Users\Mostafa\Downloads\HospitalSoftware Last Version\build-Hospital-ClinicSoftware-Desktop_Qt_5_15_1_MinGW_32_bit-Debug\
    4. Open Qt Creator and rebuild your project

    Hi @MostafaEzzat

    HospitalSoftware Last Version

    Please, please avoid project names with spaces or other special characters.

    You will run into problems sooner or later. Maybe this one is already a result of that.


  • @JKSH

    i did that just right now and still the same result

  • @aha_1980

    this's the folder name the project name doesn't have any spaces but it has "-"


  • Lifetime Qt Champion

    Hi @MostafaEzzat,

    I doesn't matter. The full path should be pure ASCII, without spaces.


  • @aha_1980

    i chagned the name of folders and .pro file to names without spaces or special characters (however when it was running on linux it was fine but i thought maybe it the issue , i even moved the folder to another directory ) but the problem still exists any change in UI FORM doesn't work


  • Lifetime Qt Champion

    Hi @MostafaEzzat,

    ok, please make sure that no ui_xxxx.h files exist in your source folder (they should only be generated in the build folder).

    This is the most common reason for problems like yours.


  • @MostafaEzzat
    You originally said "When ever i add button or checkbox or anything in any UI file form it doesn't appear", though I see there are at least a couple of buttons which do appear.

    That aside. I would think it's time you did some detective work yourself, to see where it's getting to/falling over.

    • Within Designer there is Tools > Form Editor > Preview. How does that look?

    • Have a look in the .ui file after saving (it's not read-only, is it?). Does that have your changes or not? If it has the ones you added, what is different about them compared against the couple I see which do work?

    • If the changes are going into the .ui file, have a look in the code generated into the ui_....h file. Does that have code for the new items? Again, is the code different from the ones which do work?

    Then at least we'll know where the problem actually is....

  • @JonB @aha_1980


    i mean by whenever that all ui form files changes in this specific project doesn't appear but new projects it works fine

    .ui file it's not read only, Plus the new editing like adding button or whatever it added also in .ui file but it doesn't appear when i ran the software

    and this's.ui file code about new buttons which i added for the test

       <widget class="QPushButton" name="pushButton_2">
                      <property name="text">
                     <widget class="QPushButton" name="pushButton_5">
                      <property name="text">

    and this's the form editor it apears here but it doesn't apear after running and i check the folder files there is no such a file


    Thanks for Responding

    Do you have multiple *.ui files in your project dir? Maybe you've created a backup of your design file and / or the wrong one is included in your .pro. So that the one you edit, is not the one your program is loading...

    How does your pro file look and what files do you have in your directory?

  • @MostafaEzzat
    First, do follow what @Pl45m4 has suggested.

    The ui....h files are generated during build (via uic) from your .ui into your build directory, where the *.obj files go. If your .ui file is getting updated there is something going astray during the uic build phase.

    When you change the .ui file, have a look during the Build at what commands are being executed in the Compile Output window. If nothing then you have an issue!

  • @JonB @Pl45m4

    i do have multiple .ui file in the project but there is no dublicate ui file that have the same name
    but i've multiple .pro files and there are dublicate like
    HospitalClinicSoftware "**note this not .pro it's normal file have the same name**"

    but i'm sorry i don't what's uic build exactly doing to ui files and i can't post Compile Output Result because it's more than 32000 character

    this my .pro file code
