    Thanks a lot for the example.

    But this solution using QLabel & QLineEdit will not suit my usecase.
    The content text of this LineEdit will be used as file name after replacing placeholder <COUNTER> with values from 0..N.

      @Embitel_qt
      Hi can I ask what is wrong with it ?
      Just to understand.
      It would be easy to create function to return a QString containing
      edit + Label text.

        This above mentioned is only one use case. The actual functionality of my LineEdit will contain multiple placeholder fields like <DATE>, <TIME>, etc... which can be added to the LineEdit on the current cursor position.

        So its not an option to use combination of QLineEdit & QLabel.

          I have a requirement to have a line edit which has a custom text which is non editable and another field where user can enter new text.
          Please refer the attached image. custom line edit


          | Image_<COUNTER> |

          In that image we can see that the "<COUNTER>" part should be non editable and should always be at the last position. And "Image_" is an editable text where user can enter any text.

          Is there any way to have a custom LineEdit like this.

          @Embitel_qt Will hiding the "<COUNTER>" piece of text in the code and having only a LineEdit be satisfactory? I mean storing QLineEdit as a string and adding <COUNTER> to it in code.

            @Embitel_qt
            ah, so <X> can appear anywhere in the text
            and after insertion, should not be editable?
            So you need to support all cases of
            <X>aaaaa
            aaaa<X>aaaa
            aaaa<X>

              Hi,

              To add to @mrjj do you mean something like Qt Creator's Default build directory settings in Build & Run -> General ?

                @mrjj yes you are correct <X> can be added at any position in one usecase.

                In my first use case [mode one] there will be only <COUNTER> and this should be always at the end of the LineEdit and which should not be edited. But the user can insert new characters before <COUNTER>

                In my second use case[mode two] there can be any place holder[<CONTER>, <DATE>, <TIME>, etc...] all this can be editable[no restrictions] and user can insert new characters anywhere in the LineEdit.

                    Thnaks for the inputs.
                    Now I have found a way to make my <COUNTER> non editable using the mask

                    lineEdit->setInputMask("xxxx\<\C\O\U\N\T\E\R\>");

                    Now thw problem is I am able to enter only 4 characters before <COUNTER> but i want to allow the user to enter maximum of 91 charcters.

                    What should I modify on the reg expression to achieve this?

                      @Embitel_qt Could you not just use 91 "x"s?

                      lineEdit->setInputMask("xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx1<\C\O\U\N\T\E\R>");

                        might be slightly more compact to use the fill method. :)
