brother did not post the above code is complete, please allow me to follow the master code to write a post next
------ Solution. - -------------------------------------------
sincere worship , if What do JS plugin , using C # language , and killed and I could not write . The landlord can only help Top
------ Solution ---------------------------------- ----------
landlord like this in the forum , please do not ask enough repeatedly by way of a private letter to others this will bother to ask questions others have there are user complaints Thank you for your cooperation
------ Solution - -------------------------------------------
possible after double-clicking add a pop-up screen on the Save button , the Save button click event bindings . click event pop up a Road King , the File Save action is written to the specified Road King .
------ Solution ---------------------------------------- ----
main floor refueling oh ~
------ Solution -------------------------- ------------------
just wrong , is when the mouse to drag the upper left corner will appear redrawn.

master, after the above type of run, the effect is as follows :
I made a global keyboard monitor that allows users to click on my key combination , the call directly to the window above it.
but I see :
my users want to be able in the " long-term use ," my software works in the process, hoping to " save their time as much as possible ." I saw :
Tencent QQ, clicking on the shortcut when possible : "Direct access to the picture painted area ."
above code after my initial research, I put the first post in the first 19 lines of code is modified to the following results:
public static void main(String[] args){
new CaptureScreen().doStart();
} effect after the operation , there are still " a flash in the picture above the interface and run over ," so that the user experience , not the best .
And, master, you can run the code posted brother , he takes the picture after the user unfinished areas , " double-click on the picture zone " , the following screen appears :
This is no strong QQ take pictures feature point:
QQ allows users to " click ", " save to file" option, " double- click ", " save to clipboard function called directly . "
But taking pictures in the above functions , if this functionality into my system , there will be :
allows users to feel a lot of trouble on this feature , so that my IM QQ lost in this field defects appear.
hoping to get the guidance of experts :
brother above code , how to modify , able to "Picture 1" interface lets brother called after the type , can be like QQ, Tencent fields directly choose to take a picture view of the area , and how to modify , allowing younger brother posted a second picture above code lost , optimization ?
hope to get guidance master ! ! ! ! !
------ For reference only -------------------------------------- -
thank you personally Tip # 4 floor ! ! ! !
future brother will send a private letter frequency , reduced to the original " 5% ."
Thanks again visit the guidance CSDN technology 5 # floor uncrowned emperor withiter moderator ! ! ! !
Thank you # 6 floor Lang Ching brother spiritual encouragement ! ! ! !
CSDN 's brother thanked the technical training continues to help greatly with you ! !
There CSDN! ! ! ! No brother 's dream to fruition without landing ! ! ! ! ! !
------ For reference only -------------------------------------- -
ask withiter Moderators: "Choose to take pictures of the area "
QQ achieved "post box unfinished ," " can directly select the Save button " function, is how to achieve ?
What is the use of the mechanisms and methods to do it ?
Double-click the Add to clipboard , is a relatively good implementation function.
However, after the user selects completed, the occurrence of this interface :
moderator, I ask :
QQ is " finished after the user selects ", " can make the following toolbar appears " function through what technical methods of implementation .
Tencent what method to use , what type of realization of this function
Thank CSDN uncrowned emperor

landlord , the code is still a bug, just tested , the frame is painted , you drag arrow in the upper right corner , he will be redrawn.
want to improve .
